Dgc matrix in r
WebJan 20, 2013 · We illustrate 1) a fast way of coercing a dense matrix to a sparse matrix and 2) how to copy the dimnames from the dense to the sparse matrix. WebSparse Matrices. Sparse matrices created by Matrix R package can be converted Scipy CSC matrix, and vice versa.This is often useful when you want to pass sparse matrices to Python functions that accepts Scipy CSC matrix to take advantage of this format, such as efficient column slicing and fast matrix vector products.
