COO -> CSR (Complex matrices)

Purpose
This function converts the sparse matrix in COO format to the sparse matrix in CSR format. The element order within row is same as reading order.
Parameters
[in]MNumber of rows of the matrix. (M >= 0) (If M = 0, returns without computation)
[in]NNumber of columns of the matrix. (N >= 0) (If N = 0, returns without computation)
[in]NnzNumber of nonzero elements in the matrix. (Nnz >= 0) (If Nnz = 0, returns without computation)
[in]Val()Array Val(LVal - 1) (LVal >= Nnz)
Values of nonzero elements of input matrix.
[in]Rowind()Array Rowind(LRowind - 1) (LRowind >= Nnz)
Row indices of input matrix.
[in]Colind()Array Colind(LColind - 1) (LColind >= Nnz)
Column indices of input matrix.
[out]Val2()Array Val2(LVal2 - 1) (LVal2 >= Nnz)
Values of nonzero elements of output matrix.
[out]Rowptr2()Array Rowptr2(LRowptr2 - 1) (LRowptr2 >= M + 1)
Row pointers of output matrix.
[out]Colind2()Array Colind2(LColind2 - 1) (LColind2 >= Nnz)
Column indices of output matrix.
[out]Info(Optional)
= 0: Successful exit.
= i < 0: The (-i)-th argument is invalid.
[in]Base(Optional)
Index style of Rowind() and Colind(). (default = 0)
= 0: Zero-based (C style) indexing: Starting index is 0.
= 1: One-based (Fortran style) indexing: Starting index is 1.
[in]Base2(Optional)
Indexing of Rowptr2() and Colind2(). (default = 0)
= 0: Zero-based (C style) indexing: Starting index is 0.
= 1: One-based (Fortran style) indexing: Starting index is 1.
