Subject: I used Jama for mechanical engineering and it worked prefectly


Hello Jamas,
My name is Dirk, I studied physics and work for a mechanical engineering 
company. In my free time I wrote a program to calculate bearing reaction 
forces of mechanisms. I knew that the problem was linear an, so looked 
for a linear algebra and found Jama. I found it really easy to use. I 
understood how to apply it to my problem really quickly. I was also 
happy to get a Runtime exception, as I asked it to invert a Matrix, with 
zero determinant. I was happy to see that the solution of the problem 
just writes:

Matrix mr= ma.solve(mb);

Well it took me two days to create ma and mb, but thats not your fault.

My source and applet are available at:

It is licensed under GPL.

The next problem I am facing is unfortunately a nonlinear one, so I will 
likely implement Newtons method on top of JAMA. In case I succeed and 
you are interested in the code, I will release it into public domain, so 
you can include it in JAMA.

Yours Dirk
