MATLAB: Can I get the column num of a matrix in one command

Question

Hello,

I have a matrix, named A. I want to get the the number of columns in the matrix in one command. Is this possible? It seems like it should be easy. So far, I can only do it by creating a new variable, like so:

temp = size(A); columns = temp(1,2); clear temp;

Basically, can I do the above in one command? I'm not familiar with any such function. I tried some things like:

(size(A))(1,2)

{size(A)}(1,2)

size(A)(1,2)

Thanks, Clark

P.S. – I'm a MATLAB beginner, obviously.

Answer 1

 size(A,2)   %number of columns
