If function with array - Microsoft Excel for PC

The HP test centers have run a whole host of crazy conditions. One was a test to see if their disk array could with stand the test of fire and decreased oxygen in the room the array is in. They found that even with reduced oxygen and the increased pressure from the pressure fire extinguishers the array was still able to function properly without problems. You can be sure with an HP that it will last almost anything you can throw at it. Although its recommended not to throw things at it.

Correct a #N/A error Show All Hide All This error occurs when a value is not available to a function or formula.

1. Optionally, click the cell that displays the error, click the button that appears , and then click Show Calculation Steps if it appears.
2. Review the following possible causes and solutions. Missing data, and #N/A or NA() has been entered in its place
   Replace #N/A with new data.
   Note You can enter #N/A in those cells where data is not yet available. Formulas that refer to those cells will then return #N/A instead of attempting to calculate a value.
   Giving an inappropriate value for the lookup_value argument in the HLOOKUP, LOOKUP, MATCH, or VLOOKUP worksheet function
   Make sure that the lookup_value argument (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) is the correct type of value — for example, a value or a cell reference, but not a range reference. Using the VLOOKUP, HLOOKUP, or MATCH worksheet function to locate a value in an unsorted table
   By default, functions that look up information in tables must be sorted in ascending order. However, the VLOOKUP and HLOOKUP worksheet functions contain a range_lookup argument (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) that instructs the function to find an exact match even if the table is not sorted. To find an exact match, set the range_lookup argument to FALSE. The MATCH worksheet function contains a match_type argument that specifies the order the list must be sorted in to find a match. If the function cannot find a match, try changing the match_type argument. To find an exact match, set the match_type argument to 0.
   Using an argument in an array formula that is not the same number of rows or columns as the range that contains the array formula
   If the array formula (array formula: A formula that performs multiple calculations on one or more sets of values, and then returns either a single result or multiple results. Array formulas are enclosed between braces { } and are entered by pressing CTRL+SHIFT+ENTER.) has been entered into multiple cells, make sure that the ranges referenced by the formula have the same number of rows and columns, or enter the array formula into fewer cells. For example, if the array formula has been entered into a range 15 rows high (C1:C15) and the formula refers to a range 10 rows high (A1:A10), the range C11:C15 will display #N/A. To correct this error, enter the formula into a smaller range (for example, C1:C10), or change the range to which the formula refers to the same number of rows (for example, A1:A15).
   Omitting one or more required arguments from a built-in or custom worksheet function
   Enter all arguments (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) in the function.
   Using a custom worksheet function that is not available
   Make sure that the workbook that contains the worksheet function is open and the function is working properly.
   Running a macro that enters a function that returns #N/A
   Make sure that the arguments (argument: The values that a function uses to perform operations or calculations. The type of argument a function uses is specific to the function. Common arguments that are used within functions include numbers, text, cell references, and names.) in the function are correct and in the correct position.
   

A disk array has cache memory and advanced functionality

samples of arrays in vb.net
1)
dim array(3) as integer

array(0)=1
array(1)=2
array(2)=3
array(3)=4

2) dim array() as integer

array=new integer(){1,2,3,4}

3) for two dimensional arrays add comma separation to the size

The crude solution is:
=IF(Sheet3!I2="WA",IF(Sheet3!H2="Vancouver","X",IF(Sheet3!H2="Camas","X",IF(Sheet3!H2="Ridgefield","X",IF(Sheet3!H2="Washougal","X",IF(Sheet3!H2="Stevenson","X",IF(Sheet3!H2="Hockinson","X","?City?")))))),"?State?")

Where ?City? appears when the city referenced in H2 is not part of the lookup
and ?State? appears when something other than WA appears in I2.

But there is probably a better way to do this using an array of valid values like the one below:

AL NY TX WA Birmingham Albany Abilene Camas Huntsville Buffalo Galvaston Hockinson Russell New York Houston Ridgefield Stevenson Vancouver Washougal

In the scenario you could stuff the array in another worksheet and use the HLookup function to find the "Sheet3!I2" value in the first row of this array to determine which column to look in, then VLookup "Sheet3!H2" in the column of that array to see if the city referenced exists. Of course this is a much more complex formula, but it would be easily extendible without changing the formula every time.

For mor info, see "Lookup and Reference Functions" in the Excel Help.

the best thing to do here is to separate the steps for calculating the variance into different functions. To compute the variance the first thing to do is to compute the mean or the average of the numbers in the array. so your first function will loop through each of the numbers and divide it by the length of your array. the output is the returned. The next thing to do is create another function for the variance. loop through each of the numbers again and subtract to each number the mean. square the value then add to the previous. so that means you have another variable that starts from zero and just adds the answer. after that divide it by the length of the array again and what you are going to get is the value for the variance.

To start points and lines are not shapes, and a triangle is not representable with a single function, therefore you need a function to draw shapes , given a number of points as parameters, and one to draw math functions (lines etc.).

Here is an example: Draw Line, Ellipse, Polygon ...

From website above, here is script in JS:

"<script type="text/javascript">
<!--
function myDrawFunction()
{
jg_doc.setColor("#00ff00"); // green
jg_doc.fillEllipse(100, 200, 100, 180); // co-ordinates related to the document
jg_doc.setColor("maroon");
jg_doc.drawPolyline(new Array(50, 10, 120), new Array(10, 50, 70));
jg_doc.paint(); // draws, in this case, directly into the document

jg.setColor("#ff0000"); // red
jg.drawLine(10, 113, 220, 55); // co-ordinates related to "myCanvas"
jg.setColor("#0000ff"); // blue
jg.fillRect(110, 120, 30, 60);
jg.paint();

jg2.setColor("#0000ff"); // blue
jg2.drawEllipse(10, 50, 30, 100);
jg2.drawRect(400, 10, 100, 50);
jg2.paint();
}

var jg_doc = new jsGraphics(); // draw directly into document
var jg = new jsGraphics("myCanvas");
var jg2 = new jsGraphics("anotherCanvas");

myDrawFunction();

An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier
Initializing arrays. When declaring a regular array of local scope (within a function, for example), if we do not specify otherwise, its elements will not be initialized to any value by default, so their content will be undetermined until we store some value in them. The elements of global and static arrays, on the other hand, are automatically initialized with their default values, which for all fundamental types this means they are filled with zeros
include <iostream>
using namespace std;

int billy [] = {16, 2, 77, 40, 12071};
int n, result=0;

int main ()
{
for ( n=0 ; n<5 ; n++ )
{
result += billy[n];
}
cout << result;
return 0;
}
multidimensional array pseudo-multidimensional array #define WIDTH 5 #define HEIGHT 3 int jimmy [HEIGHT][WIDTH]; int n,m; int main () { for (n=0;n<HEIGHT;n++) for (m=0;m<WIDTH;m++) { jimmy[n][m]=(n+1)*(m+1); } return 0; } #define WIDTH 5 #define HEIGHT 3 int jimmy [HEIGHT * WIDTH]; int n,m; int main () { for (n=0;n<HEIGHT;n++) for (m=0;m<WIDTH;m++) { jimmy[n*WIDTH+m]=(n+1)*(m+1); } return 0; }

Yes, there is a function in MS Excel called "sumproduct" which multiplies the componenets in an array or arrays, then totals the result, eg :

=SUMPRODUCT(D4:D20,B4:B20) ...Job done...Enjoy !
