Expand description

Compressed Sparse Column (CSC) format.

CSC is the column-compressed counterpart of CSR. It stores:

  • col_ptr[cols+1]: indices into row_idx/values for each column
  • row_idx[nnz]: row index for each non-zero
  • values[nnz]: the non-zero values

CSC is efficient for column-oriented operations and is the natural format for the transpose of a CSR matrix.
