I have a matrix with 100 x 100, from that i have to select a 50 x 70 matrix, how should i do it in matlab

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...

[ajith]

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
