[SciPy-Dev] Update NumPy for Matlab Users

[Joseph Martinot-Lagarde]

Hi,

I noticed some problems in the Wiki page "NumPy for Matlab Users" [1], but I
dan't edit it myself. Here is what i found:

- For symbolic calculation, swiginac is the proposed solution, but it has
not been updated on pypi since 2007, and the home page is down. I guess that
the standard is now sympy.

- There are multiple dead links on the page. It can be easily see on the
general informations about this page [2].

- On the pros and cons to use array or matrix in numpy about dot(), the form
dot(dot(A,B),C) should be replaced by the more readeable A.dot(B).dot(C).
Also this will have to change when the '@' operator is introduced in python 3.5.

- In "Customizing Your Environment", numpy is imported as "num", while the
commonly used name is "np".

THis page is really a great help for Matlab users, keeping it up to date is
really important !

Joseph
