Hi,
I would like to populate an 2 dimensional array, from a vector.
I think the best way to explain myself is to put some examples (with a array of [3,5] length).
When vector is: [1, 0]
[
[4, 3, 2, 1, 0],
[4, 3, 2, 1, 0],
[4, 3, 2, 1, 0]
]
When vector is: [-1, 0]
[
[0, 1, 2, 3, 4],
[0, 1, 2, 3, 4],
[0, 1, 2, 3, 4]
]

I have some geographical data, that I'm trying to parse into a usable format. The data is kept in NetCDF files, and is read out as a multidimensional array. My problem comes because the source of the geographical data has a strip of longitude on each side of the grid that overlaps the other side. That is, I have a longitude point of -1 d...
I am fetching the data using mysql_fetch_array like :
while($row = mysql_fetch_array($select))
{
$tables[] =$row;
}
Now i need this $tables array as one dimensional array only, so that i can use it in
if(in_array($val['table_name'],$tables))
{
//Some Code
}
to check for whether the $val['table_name'] is ...
Ok, I have an array like so, but it's not guaranteed to be laid out in this order all of the time...

'value' => 'value',
),
'happiness' => array(
'info' => 'some info',
'info2' => 'more info',

I read in a file with a few numbers using a scanner, and then split them using the split method. My main issue is if there is a method that can just give me ranges, probably in the math class. The numbers are currently in an array, and I wanna move those numbers and there ranges into a two-dimensional array. Could anyone give me some tip...
how would I print a 2d array in c using scanf for user input, array called grid[ ][ ] and a for loop?
say if the user types in 3 5, the output will be:

Here is the code that I have written so far (newbie here):
#include <stdio.h>
#define MAX 10
int main()
{
int grid[MAX][MAX];
int row, col;
int i,j;

I need to know how to initialize array of arrays in C#..
I know that there exist multidimensional array, but I think I do not need that in my case!
I tried this code.. but could not know how to initialize with initializer list..
double[][] a=new double[2][];// ={{1,2},{3,4}};
Thank you
PS: If you wonder why I use it: I need data str...
I am parsing a log containing nicknames and hostnames. I want to end up with an array that contains the hostname and the latest used nickname.
I have the following code, which only creates a list over the hostnames:
hostnames = []

What I would like to do in my code is something like that below:

How do I initialize a multi-dimensional array of a primitive type as fast as possible?
I am stuck with using multi-dimensional arrays. My problem is performance. The following routine initializes a 100x100 array in approx. 500 ticks. Removing the int.MaxValue initialization results in approx. 180 ticks just for the looping. Approximatel...
This is probably a completely stupid question, but i'm pretty new at objective-C and programing in general.
i'm trying to make an array of arrays but can't manage to make it work :

hello,
I'm trying to figure out how to build a multi-dimensional "array" that is:
flexible size
use 2 keys
1st key is int (flexible)
2nd key is string (kind of limited)
The use will be like:
console.writelen(array[0]["firstname"]);
console.writelen(array[0]["lastname"]);
console.writelen(array[0]["phone"]);
console.writelen(array[...

How can I recursively find the total value of all children of an array that looks something like this?
[0] => Array

[children] => Array
(
[0] => Array

I have a 10x10x10 array, z. How do I plot everything in the SAME window so that I would have the 3 plots for z(:,:,1) and below it the three plots for z(:,:,2) etc.?
This is what I have so far:
for i = 1:10
z=z(:,:,i);
figure(i)
subplot(1,2,1)
surf(z)
%code, obtain new array called "new1"...
subplot(1,2,2)

Ok, so I have a 2D Array that is initialised with values from a file (format: x y z).
My file reads in the values correctly but when adding the z value to the matrix/2DArray, I run into a segfault and I have no idea why. It is possibly incorrect use of pointers? I still don't quite have the hang of them yet.
This is my intialiser, wor...
