Hi, what would be causing following errors?
[1 3; 4 5] - [2 3] : dimension must agree Error
[1 3; 4 5] .- [2 3] : unknown operator ".-" Error
How could I operate following:
matrix A [m * n] - vector B [1 * n],
so that A(:,k) - B(k) = matrix [m * n]
This should be easy with .- operator but my MatLab refuses to cooperate.
Using MATLAB 2016a

There is no .- or .+ operator. The "." prefix is not a modifier that can be applied to any other operator: each of the operators that start with "." are defined individually.
