Fmincon requires SQP algorithm
显示 更早的评论
When I run fmincon with SQP algorithm, I get no problems. However, when I switch to 'active-set' or 'interior-point', I get the error:
OPTIMOPTIONS property 'Algorithm' must be one of the following values for fmincon:
'sqp', 'sqp-legacy'
I'm trying to use a different algorithm because the documentation says that interior-point can run faster for sparse problems, so I want to test that.

Can you post a small section of the code showing how you call optimoptions and call fmincon or solve?

Hi
Looking at the error message, I am assuming that you are using the funciton 'fmincon' with code generation, in which case 'sqp' and 'sqp-legacy' are indeed the only algorithms fmincon supports. This is mentioned in the documentation
If this is not the case, can you let me know the version of MATLAB and Operating system you are using, and if possible, share the code you are getting the error with so I can replicate the issue on my end?
Thanks

Hi,
It looks like the error shows up in the MATLAB Funciton Block. Kindly refer the following documentation link on how MATLAB Function Blocks work
In particular, note that "C/C++ code generation limitations for MATLAB Coder also apply to MATLAB Function blocks.". To use a different algorithm for your simulation you can use "coder.extrinsic" and refactor your code as mentioned in the below link
Hope this helps
