Hiall,
I am trying to embed numerical code in a mexFunction,

NumPy core functions and BLAS work fine, but calls to LAPACK

Hi,
Following on from Nathaniel's explorations of the scalar - array
casting rules, some resources on rank-0 arrays.

way of solving the problem of maintaining

Coincidently I have been having the same problem this week. Unrelated
to the problem, I would suggest looking at pymex which 'wraps' python
inside Matlab very nicely, although it has the same problem with
duplicate lapack symbols.

Dear all,
I have a code using lots of numpy.where to make some constrained
calculations as in:
data = arange(10)
result = np.where(data == 0, 0., 1./data)
# or
data1 = arange(10)
data2 = arange(10)+1.0
result = np.where(data1 data2, np.sqrt(data1-data2), np.sqrt(data2-data2))
which then

Hi,
I had many error when tring to the checkedout version and recompile.
the problem I had is that I didn't erased the build directory each
time. This cause some problem as not all is recompiled correctly in
that case. Just deleting this directory manually fixed my problem.

This makes sense of course. And yes the operation I am trying to do is
