Is there a way to solve a system with more equations than variables on matlab? For example, the function solve need the exact same number for the equations and variables.

Use the mldivide, \ operator to do a least-squares determineation of the system.
See the documentation for details.

This now appears to me to not be a regression problem but instead and optimisation problem, and one that I do not understand in enough detail to suggest a solution.
