Hello, It seems to me that the SVD implementation from ~system\packages\math\svd.ijs is inefficient for large matrices (i.e. calculating the SVD of the color matrices of an 640x500 image never ends..).
You may even try: $ svd i. 200 200 (in NumPy it takes less than a second) Before I reinvent the wheel, is there an efficient implementation of SVD available?
