How to delete an array and to free RAM

Hi. Can you help me please?
I have tried many experiments but without success.
I have a big array of arrays (matrix[][]).

After to have filled of data i measure the RAM with an utility (for example Wise Memory Optimizer).

Then i try to destroy the array in many modes, but the free RAM is still the same.

Can you help me please?
Thank you very much

Destroying and free-ing are not the same thing. Since D is a garbage collected language you probably want to do something like this:

import std.stdio;
import core.memory;

void main()
{
    long[][] array = new long[][](1024, 1024);
    writeln(GC.stats);
    destroy(array);
    GC.collect();	// Mark & Sweep
    GC.minimize();	// Free unused memory
    writeln(GC.stats);
}
