According to the discussions on the ML, they switched from GPL to MPL to enable the kind of distribution numpy/scipy is looking for. They had some hesitations between BSD and MPL, but IIRC their official stand is to allow inclusion inside BSD-licensed code. Cheers, Matthieu 2014-02-06 20:09 GMT+

[Numpy-discussion] create numerical arrays from strings

2014-02-06 Thread Alan G Isaac
NumPy matrix construction includes as a convenience feature the construction of matrices with a Matlab-like syntax. E.g., np.mat('1 2;3 4'). Is it correct that this syntax is not supported for direct (i.e., not using `mat`) ndarray creation? You may ask, where would this possibly matter? The answ

I just thought i'd mention this: Why not use Eigen? It has a full BLAS implementation and passes the BLAS test suite, and is generelly faster than MKL except on Core i7. Also, Eigen requires no build process, just include the header files. Yes, Eigen is based on C++, but OpenBLAS is parially cod
