Strictly speaking, MATLAB code cannot be described as free, libre and open-source software, because it depends on the MATLAB suite of products, which are proprietary. So, for instance, it will never be certified as FLOSS by the Open Source Initiative or the Free Software Foundation. However, it is often free of charge and you can read the code, so you might regard it as open if you have ready access to MATLAB.

Even if you don't have MATLAB, most MATLAB code runs on GNU Octave, a FLOSS clone of MATLAB.
