[SciPy-Dev] Doc error in scipy.optimize.fmin and missing info in ref guide
Mon Mar 15 18:50:34 CDT 2010
This is *very* bizarre: in View mode, Other parameters is displayed before
Returns, but in the edit frame in Edit mode, Returns is displayed above
Other parameters, but then if I preview, the preview displays it
incorrectly, even though in the edit frame, it's still correct!!! Can
someone verify this on another platform/in another browser, please? (Mine:
Windows Vista, Firefox 3.6). Thanks!
