Hi, everyone,
I assumed that C/C++ code would be faster than Matlab.
But to my surprise, I found that svd routine in matlab is much faster
than the one in vxl. I tried it on a 660*660 matrix, it took
matlab <5 seconds. While in using vnl_svd, it took about more
than 20 seconds.
Does someone has an idea about this?
Thanks in advance!
