WebApr 12, 2024 · Coordinate List (COO) Perhaps the most obvious way to store a sparse matrix is in coordinate list format. In this format, we simply store a list of triplets (row, column value) for every non-zero entry. For example, ... (CSR). Compressed Sparse Column (CSC) In machine learning, it’s much more common to retrieve columns of a matrix than it is ... WebViewed 4k times. 5. I was wondering what the algorithmic complexity of a conversion from CSC (compressed sparse column) to CSR (compressed sparse row) is? Say I have. a CSC m x m -matrix A = csc (m,m) with n non-zero elements. a CSR m x m -matrix B = csr (m,m) with n non-zero elements. Now I do the conversion from CSC -> CSR with B = convert (A ...
