Which SVD algorithm implementation is used in MATLAB?

WebJan 24, 2013 · 1. The "pinv" function of matlab is using the singular value decomposition (SVD) as part of the "Moore-Penrose Pseudoinverse" as described here, so SVD is not neccessarily an alternative to "pinv". The source code of the pinv function within Matlab is more simple than the code you posted, which may help with understanding it more easily.
