Small matrix
WebbA common trick to accelerate SVD of skinny matrices is to firstly apply a QR decomposition to it and than you do a SVD in the smaller matrix R. This gives you A = QR = QSVD, where QS is orthogonal, then QSVD is an SVD decomposition. Maybe, MATLAB does check the shape of the matrix before applying the SVD and use some similar trick.
