"linprog" is a function in MATLAB used for linear programming problems. It requires specific inputs in a certain format to work correctly. If you are getting an error message saying "Invalid input for linprog", it means that the input arguments you provided to the function are not in the correct format or are not compatible with the function.

Some possible causes of this error message are:
