Subject: URGENT: Matrix division problem?


A and B are both r*m matrix Generate matrix by random function.
Matrix A = Matrix.random(r,m);
Matrix B = Matrix.random(r,m);
I'm trying to work out the result of A.solve(B); Then, It gave me an  
exception:

Exception in thread "main" java.lang.RuntimeException: Matrix is rank  
deficient.
         at Jama.QRDecomposition.solve(QRDecomposition.java:185)
         at Jama.Matrix.solve(Matrix.java:815)

How could it be that? How can I get the right result? Thanks very
much, I need use the result in my final project. This is URGENT!

Regards
