Hello everyone,
I've been successful in writing the symbolic cholesky decomposition
for sparse matrices in O(n * c**2) time. This is a reasonable order
for sparse systems, but still the performance is not very good. Using
python bulitins, It factors a 100 * 100 Matrix with sparsity 0.57 in
961 mill

Did you make those graphs manually, or do you have some program that automates
it? It would be nice to have something that can make timing gr

I see. It would be nice to have a function, call it timings_graph() or
something, that acts similar to the timed() function. You just pass it some
lists of source code that you want to plot (or maybe multiple lists for
multiple lines), a list of x-axis values, and other information like axes
I created http://code.google.com/p/sympy/issues/detail?id=2445 for this.
