Hello Scipy-devs: The link below on building a Qt app with a Matplotlib widget is very dated. http://wiki.scipy.org/Cookbook/Matplotlib/Qt_with_IPython_and_Designer After several research/trial/error cycles, I reproduced the Qt4 plot window that you using the relevant pyplot commands. I suppose I could update the Cookbook page above, but I need editing rights. Is this still possible, or are we trying to point users to a new location? Ryan P.S.

This is a timely question. In the last few weeks, I've run into a couple things I'd like to update: * At http://wiki.scipy.org/Cookbook/LASReader, I want to add a link to the latest version, which is now on github: https://github.com/WarrenWeckesser/las * I've seen at least three occurrences (a couple on stackoverflow, and one private email) of someone using the argument 'order=15' in a call to the 'set_integrator' method of 'scipy.integrate.ode'. Presumably this is because of the suggestion in the "NumPy for Matlab Users" page on the wiki ( http://wiki.scipy.org/NumPy_for_Matlab_Users) to replace 'ode15s' with ' scipy.integrate.ode(f).set_integrator('vode', method='bdf', order=15)'. This is pointless, because the stiff solver in 'vode'--presumably the solver of interest for someone using 'ode15s'--has a maximum order of 5, and the non-stiff solver has maximum order of 12. (The maximum order of 'ode15s' is also 5; the '15' in the name refers to the variable order ranging from 1 to 5.) I can log in, but I can't edit either of those pages. Warren P.S. Here's the relevant code, in case it matters.

Along the same lines, I'd also like to mention that http://wiki.scipy.org/Cookbook/FortranIO/FortranFile and http://wiki.scipy.org/Cookbook/FortranIO give code that does the same as scipy.io.FortranFile (with a dtype-like API instead of the first page and more general use then the approach in the second page). -- Joseph Booker
