Just call the functions. Many are self-contained.

var1 = var2 * var3 + 3.14159; Instead of original: Just call the functions
function varargout = debugWrapper(varargin) disp('Input:'); disp(varargin); [varargout1:nargout] = originalPcode(varargin:); disp('Output:'); disp(varargout); end MATLAB Coder can sometimes infer input/output types from P-code usage, though not reverse the logic. 4. Migration to Python If the P-code is critical and unsupported, consider re-implementing known behavior in Python using numpy/scipy . This is often faster than fighting obfuscation.
