axis parameter support for matrix inverse function (numpy.linalg.inv) (Trac #1620)

[numpy-gitbot]

Original ticket http://projects.scipy.org/numpy/ticket/1620 on 2010-09-25 by trac user rogerbrent, assigned to @pv.

This would make it possible to compute multiple matrix inverses at once for arrays with shapes like (10, 2, 2), without having to resort to a loop.

I don't believe there is currently anything in NumPy that lets you do this.

Hi! How is it going with this implementation? I could really use it already! ;)

Unrelated from this issue, some linalg functions, including this one, are now gufuncs. They don't have an axis parameter, but any additional axis to the right are iterated.

You will need to install the development version to use the feature though.

OK thanks seberg!!
