WebJun 19, 2024 · Here for fmincon, A and B are [] and for Aeq, my matrix has just variable name as 'A'. I don't think it should make any confusion in the fmincon function operator because my Aeq is in it's place in the fmincon operator argument. WebJan 7, 2024 · There already exists a Matlab implementation of this script, so I'm essentially just trying to find a Python solver that has equivalent performance to Matlab's fmincon(). The Matlab code has analytic solutions for both the objective and constraint hessian and jacobian, which I've rewritten entirely in Python.

Then A (X) and B (X) are fine but for C (X) it must be in the form c (X) < 0 so you'll need to break it into two constraints of that form.
