WebAug 20, 2016 · The function file itself works as it is. Before, I had defined 'm' inside the function file (like m = [1 1 1]), but I think this caused the optimization routine to stay at that point. Webfminsearch only minimizes over the real numbers, that is, x must only consist of real numbers and f(x) must only return real numbers.When x has complex values, split x into real and imaginary parts.. Use fminsearch to solve nondifferentiable problems or problems with discontinuities, particularly if no discontinuity occurs near the solution.. fminsearch is …
WebWriting Scalar Objective Functions Function Files. A scalar objective function file accepts one input, say x, and returns one real scalar output, say f.The input x can be a scalar, vector, or matrix.A function file can return more outputs (see Including Gradients and Hessians)..
