Solution: Portable MATLAB cannot register compilers like MinGW. You must install the compiler directly on the host PC or use the mex -setup command to point to a portable MinGW on your USB.

For engineers, researchers, and data scientists, MATLAB is an indispensable tool. It is the gold standard for matrix computations, algorithm development, simulation (Simulink), and data analysis. However, one of the most common frustrations among users is the cumbersome installation process. A standard MATLAB installation can consume over 20 GB of disk space, takes nearly an hour to install, and litters the Windows Registry with thousands of entries. This makes it difficult to run MATLAB on a borrowed laptop, a university computer lab, or a system where you lack administrative privileges. It is the gold standard for matrix computations,
