[Numpy-discussion] Checking matrix condition number

What is the best way to make sure that a matrix inversion makes any sense before preforming it? I am currently struggling to understand some results from matrix inversions in my work, and I would like to see if I am dealing with an ill-conditioned problem. It is probably user error, but I

Re: [Numpy-discussion] performance solving system of equations in numpy and MATLAB

Thanks everyone for helping me glimpse the secret world of FORTRAN compilers. I am running a Linux machine, so I will look into MKL and openBLAS. It was easy for me to get a Intel parallel studio XE license as a student, so I have options. ___

[Numpy-discussion] performance solving system of equations in numpy and MATLAB

I recently did a conceptual experiment to estimate the computational time required to solve an exact expression in contrast to an approximate solution (Helmholtz vs. Helmholtz-Kirchhoff integrals). The exact solution requires a matrix inversion, and in my case the matrix would contain ~15000
