Hello, I was also looking for a math library to use with a research tool I was developing. I am using IronPython as the scripting language as it is easy for non programmers, who are familiar with Matlab, to quickly prototype their algorithms. I evaluated Math.NET (http://mathnetnumerics.codeplex.com/) and ILNumerics (http://ilnumerics.net/). I sill prefer if I could use NumPy and SciPy with IronPython and am interested in trying out the Enthought refactored version.
As for plotting packages, MatPlotLib (http://matplotlib.sourceforge.net/) is a great plotting library for python. It relies on NumPy. I managed to run it with IronClad, but I still prefer a fully managed version. I ended up writing a wrapper around Microsoft's charting library, so that plot(x,y) could produce a line plot etc. I would love to know if someone came across a plotting library to use with IronPython similar to matplotlib/Matlab type plotting.
