I am new to MATLAB and I am trying to minimize a function using fminsearch (line 145, caviaropt.m). But when I do that an error pops "Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 3-by-1" . The function gives a 3x1 vector at initial points but the function has to return a scalar in order to apply fminsearch. How can I solve this issue?
Any help is much appreciated!
