In the name of God

Hello Dear Pagan

Thanks for your usefull comment. That was very exciting for me.

I have Maple16-64bit and I am a Win7-64bit user.

I did exactly the instructions you write; I mean

> restart;

> M:=Matrix(2000,datatype=float[8]):

> kernelopts(gcbytesavail),kernelopts(gcbytesreturned);                               0, 0 > M:='M':

> dummy1: dummy2: dummy3:

> gc();

> kernelopts(gcbytesavail),kernelopts(gcbytesreturned);                        32330756, 32012956

but gcbytesreturned is zero!!!

I think, It's another instruction instead of dummy in Maple16

best Regards
