# MATLAB: How to obtain the minimum values of an array

array

I'm trying to get the minimum values of three vectors. Assuming that the length of the vectors is 1×4, I need to get 4 minimums. Also one of the vectors has as values a constant. I'm attaching the code. The important part is on lines 12 to 15.
