Hi,
I'm testing the 3.0-beta2 version, but I have a problem with JacobiSVD class.
I also tried the example written here: http://eigen.tuxfamily.org/dox-devel/cl ... biSVD.html
I receive these warnings (with Visual Studio 2008):

Code: Select all

How can I resolve this problem?
Thanks in advance! =)

Thanks, warning fixed.

I still have the warnings...
Anyway, I resolved using this code:

Code: Select all

  m_computeFullU = (computationOptions & ComputeFullU) != 0;
  m_computeThinU = (computationOptions & ComputeThinU) != 0;
  m_computeFullV = (computationOptions & ComputeFullV) != 0;
  m_computeThinV = (computationOptions & ComputeThinV) != 0;


Thank you!

This is a seriously broken warning. I'm adopting your fix.
