Whether there is a way to write the constrains and object function in a matrix way

[GehenHe]

Hi,is apmonitor support optimize a matrix?
For I need to optimize a matrix X , and I don't want to rewrite the constrains for each elements of X, whether there is a way to write the constrains and object function in a matrix way?

APMonitor does support matrix multiplication with the axb object but the parameters are constants. I'd recommend the GEKKO package (https://github.com/BYU-PRISM/GEKKO). It is available with pip install gekko. This package allows models to be built directly in Python. More information is available at http://gekko.readthedocs.io/en/latest/

APMonitor probably isn't the right solution if you need to solve an optimization problem with complex numbers. The MATLAB solver fmincon may be able to handle complex numbers: https://www.mathworks.com/matlabcentral/answers/265883-fmincon-optimization-for-complex-vectors There may also be clever ways to divide variables into two parts and solve a complex numbered system with real values only.
