[jira] [Created] (MATH-947) SingularValueDecomposition constructor
blocks with NaN in the matrix
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
