Hello all:
First a quick question on calling lapack functions.
It seems that scipy does not have a function for
calculating the reciprocal condition number of a
matrix. If I can pass a matrix to the lapack function
DGECON I can get the values I need, but I dont
understand the syntax for calling lapack functions. I
read about lapack.get_lapack_funcs but still am
confused. Could someone offer a simple example to
call a lapack function from python?
Second, with some effort I got AMD, numpy, and scipy
to install on my AMD 64 bit machine using the amcl
libs. I did install cblas but as far as I could tell,
neither numpy nor scipy linked to the libraries. I
did get one error when I ran the tests after
installing. If anyone is interested, here it is:
> ----------
> FAIL: check_cdf
> (scipy.stats.tests.test_distributions.test_f)

----------------------------------------------------------------------
> Traceback (most recent call last):

> args = (1.0151727844701894, 1.8204690429811792)
> -----------------------
Also, for what its worth, the only way I could get
numpy to install correctly was by using gfortran as
the compiler and linking to the gfortran libs.
