采纳的回答： Walter Roberson

For example, I have a matrix:

a = [1.02 3.04 5.06 0.56; 4.01 2.09 4.07 0.87; 1.03 3.05 4.09 2.08]

and say I want to delete the first column from each row.... how can I do this??.. what will be the syntax for it??...

a = a(:,2:end);

a = (reshape(a',length(a(1,:)),length(a(:,1)-1)))';

or something like that.
