Hi, I need to use the reshape command to create a 3 × 4 matrix and fill it with the next values starting from 10.
A = 10:20;
B = reshape(A,[3,4])
I'm trying to do it with what command but I get an error: To RESHAPE the number of elements must not change. How to do it correctly?

"A" only has 11 elements. You want B to have 12 elements (3*4). If you set A = 10:21, for example, it will work.
