delete column with known col indices

Hi
I want to delete several columns in a matrix and get the resulting matrix without using loops, what is the fastest way to do this. I saw some posts but didn't understand them.

For example
1 2 3 4 5
6 7 8 9 10

I want to delete columns [1 3] and get
2 4 5
7 9 10

what is the fastest way to do this.

Thanks
Diego

A = [1 2 3 4 5;6 7 8 9 10]
C = [1 3]
A(:,C) = []
