sir i have a matrix 10x10 and i want to remove row and col no 3,5,7,8,10 and wants to get 5X5 matrix there are different ways to truncate but i need that way in which original matrix should remain same and truncation process should done in a new metric, one solution of truncation..... B=A(:,2:7); C=B(2:7,:); that means we want entities from 2 to 7 remaining will truncate. but i need a specific row and col to delete........ and net matrix with new name???/?

Rajinder singh wrote a flag that is more of a comment.
we can also delete columns by this method, but in case of columns deletion, the colon has to come first in the bracket, then comes the cols_to_delete
