[Numpy-discussion] Re: status of long double support and what to do about it

2022-12-14 Thread Carl Kleffner
Hi Scott, may I ask you which kind of vector / matrix operation in extended precision (np.longdouble) is supported in 'pint' ? It can't be backed by the underlying blas library as extended precision functions are not supported there. Carl Am Di., 6. Dez. 2022 um 15:24 Uhr schrieb Charles R Harri

Hi, Maybe a short introduction like this one: https://albertcthomas.github.io/good-practices-random-number-generators/ could help to get the idea. Cheers Carl Am Fr., 15. Okt. 2021 um 13:51 Uhr schrieb Ilhan Polat : > As a cosmic coincidence this happened to me yesterday. My goal: generate > n

Re: [Numpy-discussion] C-coded dot 1000x faster than numpy?

2021-02-23 Thread Carl Kleffner
The stackoverflow link above contains a simple testcase: >>> from scipy.linalg import get_blas_funcs>>> gemm = get_blas_funcs("gemm", >>> [X, Y])>>> np.all(gemm(1, X, Y) == np.dot(X, Y))True It would be of interest to benchmark gemm against np.dot. Maybe np.dot doesn't use blas at al for whateve
