LinAlgError [source] ¶ Generic Python-exception-derived object raised by linalg functions. Compute the (multiplicative) inverse of a matrix. [Fixed] singular matrix: resolution failed at diagonal %d Below I generate a square matrix with rank lower than its size, but np.linalg.inv does not throw an error as expected (because said matrix is singular) Reproducing code example: … Ensure aperture photometry returns NaN if all FLUX or FLUX_ERR pixel values are NaN (fixes #648) #651. It's not computationally singular, just almost singular :) A more reliable check is matrix_rank, which tries to account for roundoff error and gives 15 in this case, which will tell you that there is a problem. Note that rank preserving matrix factorizations tend to be computationally expensive, so are not used by default.
