This is required for the Dot impl in @pmarks branch, which itself is dependent on rust-lang/rust#55437

Great!
As you said, it will be better to split into dense and sparse part, and svddc refactoring part possibly.
This PR can be merged by omitting sparse part.
Before implementing sparse part, we need to create nightly CI for testing it, and CI setting will be my task.

This should probably be 2 PRs, but I wanted to post it here for discussion first.
First, I moved
svddctosvd_dc(so we can havesvd_rand), and movedsvd_dcunder theSVD_trait, de-duplicating a lot of logic.I also implement
svd_rand, though this version does not have the changes required for complex numbers, which we definitely want. This is dependent on a set of complex trait requirements that just works forArray2, but is needed for sparse representations of matrices (be they sprs or a low-rank representation likeM = u.dot(&v).I also add an optional feature on sprs, though right now only @pmarks branch of sprs implements the Dot traits required to make
svd_randfunction.
