Subject [jira] [Created] (MATH-947) SingularValueDecomposition constructor blocks with NaN in the matrix
Date Thu, 14 Mar 2013 13:02:13 GMT
Matti Franssila created MATH-947:
------------------------------------

             Summary: SingularValueDecomposition constructor blocks with NaN in the matrix
                 Key: MATH-947
                 URL: https://issues.apache.org/jira/browse/MATH-947
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.0
         Environment: jdk1.7.0_13 32bit, Netbeans 7.2.1, Win7 x64
            Reporter: Matti Franssila
            Priority: Critical


//Create coefficient (A) Matrix
        RealMatrix coefficients =
            new Array2DRowRealMatrix(coeffs);

               SingularValueDecomposition svd = new SingularValueDecomposition(coefficients);

//When coeffs is a 2x2 matrix with all elements Nan, the constructor blocks indefinitely /w
100% CPU usage
