Hello,

I've been looking for some comments on what I've created, and maybe it's 
nothing really special, but I'd like to hear that from reputable folks. 
To this end, I've created a demonstration page where the user can enter 
a matrix of any size and see the (pseudo-)inverse. The discussion on 
some of the other pages compares my solution with that of the 
Moore-Penrose and contrasts it with the standard Gauss-Jordan.

My site is run from my house: http://aktzin.com/InverseDemo.jsp I've no 
idea if I'm stepping on the toes of giants, or if this is unique on the 
'net. The other sites I've visited all require a non-zero determinant 
and square. Real data isn't always like that, of course.

I offered this to the Java math folks a few years ago but they didn't 
know how it would be used. The C++ version (also available from the 
site) is rather out of date, but will work for whatever type you want. 
The Java currently only works with doubles, because I haven't taken the 
time to learn how to create an object of the instantiation type in the 
generic.

The demonstration page was finished this weekend, but was promised to 
someone in France a couple years ago. Please let me know what you think.
