mkl_sparse_?_create_coo
Creates a handle for a matrix in COO format.
Syntax
stat = mkl_sparse_s_create_coo (A, indexing, rows, cols, nnz, row_indx, col_indx, values)
stat = mkl_sparse_d_create_coo (A, indexing, rows, cols, nnz, row_indx, col_indx, values)
stat = mkl_sparse_c_create_coo (A, indexing, rows, cols, nnz, row_indx, col_indx, values)
stat = mkl_sparse_z_create_coo (A, indexing, rows, cols, nnz, row_indx, col_indx, values)

Description
The mkl_sparse_?_create_coo routine creates a handle for an m-by-k matrix A in COO format.
The input arrays provided are left unchanged except for the call to mkl_sparse_order, which performs ordering of column indexes of the matrix. To avoid any changes to the input data, use mkl_sparse_copy.
Input Parameters
- <!-- -->indexing
-
sparse_index_base_t.
Indicates how input arrays are indexed.
SPARSE_INDEX_BASE_ZERO
Zero-based (C-style) indexing: indices start at 0.
SPARSE_INDEX_BASE_ONE
One-based (Fortran-style) indexing: indices start at 1.
- rows
-
C_INT.
Number of rows of matrix A.
- cols
-
C_INT.
Number of columns of matrix A.
- nnz
-
C_INT.
Specifies the number of non-zero elements of the matrix A.
Refer to nnz description in Coordinate Format for more details.
- row_indx
-
C_INT.
Array of length nnz, containing the row indices for each non-zero element of matrix A.
Refer to rows array description in Coordinate Format for more details.
- col_indx
-
C_INT.
Array of length nnz, containing the column indices for each non-zero element of matrix A.
Refer to columns array description in Coordinate Format for more details.
- values
-
C_FLOAT for mkl_sparse_s_create_coo
C_DOUBLE for mkl_sparse_d_create_coo
C_FLOAT_COMPLEX for mkl_sparse_c_create_coo
C_DOUBLE_COMPLEX for mkl_sparse_z_create_coo
Array of length nnz, containing the non-zero elements of matrix A in arbitrary order.
