Hi all, I have two questions regarding sparse matrices:
1. I have a sparse Matrix: val sparseMatrix = SparseMatrix.fromCOO(row, col, csvInput.collect()) and now I would like to extract all values that are in a specific row X. How would I tackle that? flatMap() and filter() do not seem to be supported in that case. 2. I want to drop/delete one specific row and column from the matrix and therefore also reduce the dimension. How is the smartest way to do so? Thanks in advance! Lydia
