This function returns the fields of the sparse matrix descriptor spMatDescr stored in COO format (Array of Structures layout).

Parameters

• spMatDescr: Sparse matrix descriptor.
• rows: Number of rows of the sparse matrix.
• cols: Number of columns of the sparse matrix.
• nnz: Number of non-zero entries of the sparse matrix.
• cooRowInd: Row indices of the sparse matrix. Array nnz elements.
• cooColInd: Column indices of the sparse matrix. Array nnz elements.
• cooValues: Values of the sparse matrix. Array nnz elements.
• idxBase: Index base of cooRowInd and cooColInd.
• valueType: Datatype of cooValues.
