seq-like methods in Transpose? (Migrating from Scalala to Breeze)

[Juan Miguel Cejuela]

Hi group,

I’m migrating a third-party library that used scalala to breeze. Before row vectors were used extensively. From the quick start I read that row vectors are now Transposes of vectors in scala.

When I do the pertinent type changes, compilation problems arise since it seems a Transpose doesn’t implement (mutable) sequence methods, such as: update, max, argmax, toArray, …

Am I missing something? Is there any implicit that I should include?

Thanks!

Yeah, you basically have to unwrap the transposes with .t.

I'm starting to regret the whole Transpose thing. 90% of the reason for its existence was to make dv.t * dv be dot product without having two DenseVector types lying around, which was a huge maintenance headache.  

I think I have a better solution now (using a type parameter on DenseVector and adding aliases) but it'll take a lot of cycles.
