LAPACK and Atlas do not AFAIK have convolution routines -- that's not linear algebra. MKL on the other hand would have some. The implementation in Numpy is the straightforward one, without SIMD etc. For large datasets, scipy.signal.fftconvolve should be faster. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
