Found RedSVD Header file slower than command line

[ronagrawal]

Hi
If I am using command line input
"redsvd -i -o -r -m -f "
I am able to calculate redsvd very fast.

However If i am implementing the header file & Eigen Libaries in c++, my program execution is very slow. What could be the reason behind it?

I am usign
mat.setFromTriplets(tripletList.begin(), tripletList.end())
to store the matrix
and calling
RedSVD::RedSVD S(mat);
to calculate SVD

Thanks

This is not a support form for the original redsvd code.
