The overhead of the np.matrix class is quite high for small matrices. See
for example the following code:
import time
import math
import numpy as np
def rot2D(phi):
c=math.cos(phi);
return np.matrix(c)
_b=np.matrix(np.zeros( (1,)))
def rot2Dx(phi):
global _b
r=_b.copy()
c=mat

I'm happy to announce the release of pyMIC v0.6.
pyMIC is a Python module to offload computation in a Python program to the
Intel Xeon Phi coprocessor. It contains offloadable arrays and device
management functions. It supports invocation of

over a year's worth of enhancements and bug fixes in the 1.10.0 release, so
please give this rele

clang: src/multiarray/cblasfuncs.c
clang: error: no such file or directory: 'src/multiarray/cblasfuncs.c'

if so then please upload a b2, so it will avoid confusion with those
who have downloaded a b1-pre-fix and those with a b1-post-fix
