WebDec 7, 2024 · That would give users an opportunity to calculate for several proposed x in vectorized form. At present, fmincon is defined as passing in the x information in the same shape as x0 was passed to it. A 'vectorized' flag would, I suspect, off more optimization possibilities for the objective function, whether on CPU or GPU.
