Very small numbers can cause a divided by zero error in SVD #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When decomposing a matrix with elements that are very small there are 
situations where this can cause a divided by zero error.  A potential fix has 
been committed that changes the way exceptional shifts, wilkinson step, and 
other parts of the code are handled.  Also more checks are in place for zeros.

The fix is current being verified.
