Hello, I'm a Japanese student.
Forgive me for my poor English.
Finding that javax.vecmath.GMatrix.SVD() doesn't work right,
I was looking for a java class that can calculate SVD.
And now I'm using Jama. Thankyou very much.
I have a question about the limitations in Jama.
I tried the SVD calculation to a 12,000-by-25 matrix and it worked well.
But when it came to a 24,000-by-125 matrix, it didn't.
The java program kept on running one night but there was no progress.
It was just as if it went into a loop than it can never get out.
I don't think it's something about the amount of memory.
I have 320MB on my win2000 PC, and that time, only 240MB was used.
My Environnment is Windows2000 + jdk1.3
If there are any limitations about the size of the matrix,
would you please tell me.
