In many functions i cant generate with different dimensions in the row and columns (i.e)i can generate a dct matrix with the dimensions of 10 x 15..so that i can generate a 15 x 15 and can i select a 10 x 15 matrix from it...

for example a= 15 x 15 matrix then
you do
a=a(1:10,1:15);
then check a data values shows 10x15
or
b= a(1:10,1:15);
then check b data values shows 10x15
