I have load 100x100 mat file into workspace. How can I extract certain range of values for example (5:10)x(5:10) from the workspace?

Please clarify what you want

You have a matrix A:

A = rand(100,100);

You want only the 5th through the 10th elements, you can do that using the colon operator:

B = A(5:10,5:10);

Hello. I've tried to extract it as A(264:271 , 267:274) but the output is not what I expected. May I know what is the problem with this?
