Add a value to the last column in a matrix

How do you go about adding a value to the last column of a matrix.

For example if I have a 3x3 matrix where all the values are 1. How do i select and add 3 to the third column such that the last column has values of 3 instead of 1.

Regards, Jerry

Simply use the accessor for matrix to get the vector you want to modify (i.e. last column vector) and create the vector you want to put in:

mat(:, 3) = [1; 2; 3];

And in your case you want to fill the vector with a single value, you can use:

mat(:, 3) = 3*ones(1, 3);

or

mat(:, 3) = 3;
