Re: [SciPy-Dev] Speeding up scipy.special.erf()?

I have not tested this, but I suspect that the MATLAB routine is using the erf implementation from the Intel Math Kernel Libraries (MKL).

There is a function in MKL called vdErf that takes a vector of doubles and is likely tuned to the hardware. This could be linked to NumPy with similar speed benefits.

The uvml module https://github.com/geggo/uvml <https://github.com/geggo/uvml> exposes the fast MKL/VML erf implementation to numpy. Unfortunately, no binaries available. Gregor
