Use matrix[2][2] instead of matrix[2,2].
OK.

Hi.
Is there a Built-in function (no code, only a built-in function)
that transform a linear array to a Matrix?
For example:
From
[10,20,30,40,50,60,70,80,90,100,110,120];
To
[
[10,20,30],
[40,50,60],
[70,80,90],
[100,110,120]
];
Thank You very much
Cheers.

Hi.
I am very new to D Language and I apologize for my bad question.
Why the followin code gives me the error?
Error: only one index allowed to index `int[3][3]`
import std.stdio;
import std.array;
void main()
{
int[3][3] matrix;
matrix[2,2]=99;
}

Hi,
i have seen that a simple operation (in a loop) is faster than
the equivalent UDF.
The first example takes 4 seconds, the second example takes 16
seconds.
Local variables influence the speed of execution?
Thank you very much.

Hi.
How can I know the amount of RAM allocated by a vector?
For example:
string[8][1000] array;
for(int i=0;i<1000;i++) {
array[i]=["","","","","","","",""];
}
how can I know the amount of bytes of above matrix?
Can I clean the memory ofter his use, without
28 matches
