CSC -> CSR (Complex matrices)

Purpose
This routine converts the sparse matrix in CSC format to the sparse matrix in CSR format.
Parameters
[in]MNumber of rows of the input matrix. (M >= 0) (if M = 0, returns without computation)
[in]NNumber of columns of the input matrix. (N >= 0) (if N = 0, returns without computation)
[in]Val()Array Val(LVal - 1) (LVal >= Nnz) (Nnz is the number of nonzero elements of input matrix)
Values of nonzero elements of input matrix.
[in]Colptr()Array Colptr(LColptr - 1) (LColptr >= N + 1)
Column pointers of input matrix.
[in]Rowind()Array Rowind(LRowind - 1) (LRowind >= Nnz)
Row 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)
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.
(default: Assumes 1 if Colptr(0) = 1, 0 otherwise)
[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.
