Function interface for svds #3

Closed andland closed 8 years ago

andland commented 8 years ago

Is it possible to implement the function interface for svds? Or is there a non-trivial way to use the eigs function interface to calculate the SVD with a function? I believe one would need to provide two functions: A %*% x and t(A) %*% x. At least that is what the PROPACK library has.

Yeah, this is workable. I plan to implement this feature in the next version. Thanks.

This feature has been added in the most recent version. See the bottom of the README page.

The new version has been submitted to CRAN, so I think we can close this issue.

Awesome, thanks!!
