mkl_sparse_?_create_csr
Creates a handle for a CSR-format matrix.
Syntax
stat = mkl_sparse_s_create_csr (A, indexing, rows, cols, rows_start, rows_end, col_indx, values)
stat = mkl_sparse_d_create_csr (A, indexing, rows, cols, rows_start, rows_end, col_indx, values)
stat = mkl_sparse_c_create_csr (A, indexing, rows, cols, rows_start, rows_end, col_indx, values)
stat = mkl_sparse_z_create_csr (A, indexing, rows, cols, rows_start, rows_end, col_indx, values)

Description
The mkl_sparse_?_create_csr routine creates a handle for an m-by-k matrix A in CSR 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.
- rows_start
-
C_INT.
Array of length at least rows. This array contains row indices, such that rows_start(i) - indexing is the first index of row i in the arrays values and col_indx. The value of indexing is 0 for zero-based indexing and 1 for one-based indexing.
Refer to pointerB array description in CSR Format for more details.
- rows_end
-
C_INT.
Array of at least length rows. This array contains row indices, such that rows_end(i) - indexing - 1 is the last index of row i in the arrays values and col_indx. The value of indexing is 0 for zero-based indexing and 1 for one-based indexing.
Refer to pointerE array description in CSR Format for more details.
- col_indx
-
C_INT .
For one-based indexing, array containing the column indices plus one for each non-zero element of the matrix A. For zero-based indexing, array containing the column indices for each non-zero element of the matrix A. Its length is at least rows_end(rows - 1) - indexing.
The value of indexing is 0 for zero-based indexing and 1 for one-based indexing.
- values
-
C_FLOAT for mkl_sparse_s_create_csr
C_DOUBLE for mkl_sparse_d_create_csr
C_FLOAT_COMPLEX for mkl_sparse_c_create_csr
C_DOUBLE_COMPLEX for mkl_sparse_z_create_csr
Array containing non-zero elements of the matrix A. Its length is equal to length of the col_indx array.
Refer to values array description in CSR Format for more details.
