説明

Hello!

I have a CSC sparse matrix and a DenseVector. I want to do the operation transpose(DenseVector)*CSCMatrix, which should yield a Transpose(DenseVector). As far as I could see, this method is not implemented. This seems implemented for transpose(SparseVector)CSCMatrix (method canMulSVt_CSC_eq_SVt in CSCMatrixOps.scala ), but I could not find a DenseCSC method. Can someone confirm this implementation is not present in Breeze? If so I add it

cheers

初心者向け度: 60
調査方針: Investigate the existing multiplication methods in CSCMatrixOps.scala, specifically the canMulSVt CSC eq SVt method used for Transpose(SparseVector) * CSCMatrix. Implement a similar method for Transpose(DenseVector) * CSCMatrix, ensuring the result type is Transpose(DenseVector). Add unit tests following the library's testing conventions.
