WebMar 1, 2024 · The econ version of SVD (at least MatLab) will only cut the basis-vectors, that will not be used since they do not lie in the image of the matrix. However, if you form a (econ) QR-Decomposition, you could use the upper part of R (the non-zero-part) and do a SVD on that. On my amchine, that is considerably faster, than directly using SVD. Share … WebThe economy-sized decomposition svd (A,"econ") returns S as a square matrix of order min ( [m,n]). For complete decompositions, svd (A) returns S with the same size as A. Additionally, the singular values in S are returned in a column vector or diagonal matrix depending on how you call svd and whether you specify the outputForm option:
