Webqsymm.linalg.rref(m, rtol=0.001, return_S=False) [source] Bring a matrix to reduced row echelon form. Parameters m ( 2D numpy.ndarray) – The matrix on which to perform row reduction. rtol ( float) – The tolerance relative to the largest matrix element for what is considered a zero entry. WebUsing python’s timeit tools I timed both your for loop (with numba and flags) as well as linalg.norm (no numba). On my end, numba takes ~0.366 seconds for an array of size (4,10240000), and linalg.norm takes ~0.201 seconds. In fact, numba is even faster when I remove parallel=True, bringing it to about the same time as linalg.norm.
