How to replace range in matrix with specific value?

Hi,

I have for example a matrix:

A= [1 2 3; 2 3 4, 4 5 6]

1 2 3

2 3 4

4 5 6

how do I replace all values in col 1 and 2 to 5 so it would be

5 5 3

5 5 4

5 5 6

Thanks

You can do that like so:

A = [1 2 3; 2 3 4; 4 5 6];
A(:,1:2) = 5

A = 3×3

5 5 3 5 5 4 5 5 6
