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.

If you're really sure about the array and matrix dimensions/types.
You can use a cast:

    int[] a = [10,20,30,40,50,60,70,80,90,100,110,120];

    int[3][] m1 = cast(int[3][]) a;
    writeln(m1);

A better way is using the function chunks;

    import std.range;

    auto m2 = a.chunks(3);
    writeln(m2);
