■R2017a and later versions:
Although it is not the Independent Component Analysis (ICA) itself, Statistics and Machine Learning Toolbox has the function rica , which is the derivation of the ICA called Reconstruction ICA (RICA). This algorithm is based on ICA, but with a reconstruction cost. Here, the cost means a penalty or regularization term.
By replacing the normal orthonormal constraints of the ICA with the smoother cost term, this algorithm can improve the convergence speed of computation and enables feature extraction with not local but global orthogonality. The details of the algorithms of ICA with the reconstruction cost, please refer to the following documentation:

The ability to perform Independent Component Analysis is not available in MATLAB.
