I am solving a multi-dimensional function using fsolve. I am trying to solve it using GA tool but then reverted and wanted to run the function using fsolve once again. Although I removed the GA solver, an error message "Singular Matrix in LUDCMP -STOP" keeps popping up in the command line. Is there a way to stop this? I have closed all the windows and even tried to run another code and the error message keeps coming. It seems the GA tool changed a setting or so. I appreciate your inputs.
I am using MATLAB R2020b, if that helps.

I copied and pasted the code in another directory and it did not show the error message anymore. I do not know what was wrong!

Something in the original directory was interfering
