Maximal number of iterations (540) exceeded

Key: MATH-327
URL: https://issues.apache.org/jira/browse/MATH-327
Project: Commons Math
Issue Type: Bug
Environment: Windows 7 (32-bit) JDK 1.6_16
Reporter: Mansoor Ahmed Khan
Priority: Critical
I have a matrix of size 49x19 and when I apply SVD on this matrix it raises the
following exception. The problem which I am facing is that SVD works for some
matrix and doesn't work for others. I have no clue what is the possible reason.
Exception::
org.apache.commons.math.linear.InvalidMatrixException:
org.apache.commons.math.MaxIterationsExceededException: Maximal number of
iterations (540) exceeded
