      Description

      //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
