The matrix inverse is a cornerstone of linear algebra, taught, along
with its applications, since high school. The inverse of a matrix
\$latex A\$, if it exists, is the matrix \$latex A\^{-1}\$ such that
\$latex AA\^{-1} = A\^{-1}A = I_n\$. Based on the requirement that the
left and …

This was accomplished by building on what I described in my recent
posts, specifically the extensions to Fabian’s [memory_profiler][] that
you can find in my fork, but they will be merged upstream soon. The
key element is the %magic_memit function whose …

In my last post I mentioned that I’m not satisfied with the current
state of %memit, because some more complicated numerical function
calls make it crash. I will start this post with a reminder of a pretty
important bug:

[On MacOS X (10.7 but maybe more), after forking …
