21 Aug 2014 Fast Symmetric Positive Definite Matrix Inverse Uses LAPACK, Cholesky to invert real, positive definite, symmetric matrix. Faster than inv. Author: Eric Blake

Thanks for the updated code, Eric!
Works like a charm.

On a side note, and I think it is worth mentioning in the description that the speed-up is noticeable when the matrices are large (in the current example they are small). In my case, I have to solve a big least-squares problem - and invChol, literally, saves the day.

Excellent code, simple yet efficient, thank you!

One comment. When I compile this in Linux (x86) on MATLAB 2009, I'm getting these warnings:

/opt/matlab/bin/mex invChol_mex.c -lmwlapack

invChol_mex.c: In function ‘mexFunction’:
invChol_mex.c:75: warning: implicit declaration of function ‘dpotrf_’
invChol_mex.c:87: warning: implicit declaration of function ‘dpotri_’
invChol_mex.c:111: warning: implicit declaration of function ‘spotrf_’
invChol_mex.c:123: warning: implicit declaration of function ‘spotri_’

Not critical, of course, but still.

01 Dec 2010 Zernike calculator Graphical calculator showing Zernike polynomials for a variety of aperture shapes. Author: Christina Dunn

Suggestion:
1. Your program uses polar3d, but you have not mentioned this.

2. Bugreport: line 234:
it is::: function rectZernikeButton_Callback(hObject, ~, handles)

it should be:::: function rectZernikeButton_Callback(hObject, eventdata, handles)

3. it crashes my old Matlab 7.4 on Linux: Segmentation violation detected :-)

But it works on newer versions (I have 2009b at Uni). Documentation is awesome (unlike many other tools).

06 May 2010 Using Doxygen with Matlab Extracts automatically comments from your Matlab .m files using Doxygen to generate documentation Author: Fabrice

Fabrice, thank for the program!
The only question I have: is it possible to comment variables by such script? I mean, if I have

a = [1,2,3,4]; %> this is a description of the var

can it be displayed in doxygen-generated docs?
