Web1 day ago · In the algorithm I'm trying to inverse some matrix, the result is that Matlab inverse the matrix as it should do but Python (using numpy.linalg) says that it cannot inverse singular matrix. After some debugging, we found out that in Matlab the determinant of the matrix was 5.79913020654461e-35 but in python, it was 0. Thanks a lot! Webtorch.linalg.solve () computes A.inv () @ B with a numerically stable algorithm.
