Description

There are many NLP solvers that can interface with Matlab, potentially allowing users to try to solve problems using a core solver other than FMINCON. Two possible interfaces are with Knitro and SNOPT, links below:

Knitro: https://www.artelys.com/tools/knitro_doc/3_referenceManual/knitromatlabReference.html https://www.artelys.com/tools/knitro_doc/1_introduction/installation.html

Research direction
Investigate the existing OptimTraj solver interface in Matlab, likely in the main source files. Study the Knitro and SNOPT Matlab API documentation linked in the issue. Determine how to integrate these solvers as alternatives to FMINCON, focusing on common interface patterns. Consider writing a wrapper function that converts OptimTraj's problem structure to the solver's expected format and returns results in a compatible structure.
