[sage-devel] side-by-side comparisons

2007-08-11 Thread William Stein
Hi, Josh Kantor just pointed this out to me: http://www.scipy.org/NumPy_for_Matlab_Users?highlight=%28matlab%29 It gives a comparison of numpy/scipy and matlab and a translation of matlab commands to numpy/scipy which may be useful if you run into people considering SAGE/python over matlab.

[sage-devel] Yacas in Sage?

2007-08-11 Thread znmeb
Has anyone considered adding Yacas to Sage? They just released version 1.1.0, and have an ambitious road map that seems at least philosophically compatible with Sage. See http://yacas.sf.net/ and
