Re: Re: Doubt in the EigenValueProcedure in DenseMatrix.java

[aa...@buffalo.edu]

Hi Edward,
           I have a couple of more questions about the Jacobi Eigen Value
procedure. As of now I think all the eigen values are stored in the eival:value
column in the JacobiEigenValue table. So to return the eigen values all I have to
do is at the end of the function, I have to write return JacobiEigenValue; 

I tried this and it did not compile. What is the mistake ?
