CSC -> COO (Complex matrices)
- Purpose
- This routine converts the sparse matrix in CSC format to the sparse matrix in COO format.
The order of elements of output matrix will be same as val[] array of input matrix.
- Parameters
-
| [in] | m | Number of rows of the matrix. (m >= 0) (if m = 0, returns without computation) |
| [in] | n | Number of columns of the matrix. (n >= 0) (if n = 0, returns without computation) |
| [in] | val[] | Array val[lval] (lval >= nnz) (nnz is the number of nonzero elements of input matrix)
Values of nonzero elements of input matrix. |
| [out] | colptr[] | Array colptr[lcolptr] (lcolptr >= n + 1)
Column pointers of input matrix. |
| [in] | rowind[] | Array rowind[lrowind] (lrowind >= nnz)
Row indices of input matrix. |
| [in] | base | Indexing of colptr[] and rowind[].
= 0: Zero-based (C style) indexing: Starting index is 0.
= 1: One-based (Fortran style) indexing: Starting index is 1. |
| [out] | val2[] | Array val2[lval2] (lval2 >= nnz)
Values of nonzero elements of output matrix. |
| [out] | rowind2[] | Array rowind2[lrowind2] (lrowind2 >= nnz)
Row indices of output matrix. |
| [out] | colind2[] | Array colind2[lcolind2] (lcolind2 >= nnz)
Column indices of output matrix. |
| [in] | base2 | Indexing of rowind2[] and colind2[].
= 0: Zero-based (C style) indexing: Starting index is 0.
= 1: One-based (Fortran style) indexing: Starting index is 1. |
| [out] | info | = 0: Successful exit.
= i < 0: The (-i)-th argument is invalid. |
