COO -> CSC

Purpose
This routine converts the sparse matrix in COO format to the sparse matrix in CSC format.

The order of elements in each column of output matrix will be same as input matrix.
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.
[in]val[]Array val[lval] (lval >= nnz)
Values of nonzero elements of input matrix.
[in]rowind[]Array rowind[lrowind] (lrowind >= nnz)
Row indices of input matrix.
[in]colind[]Array colind[lcolind] (lcolind >= nnz)
Column indices of input matrix.
[in]baseIndexing of rowind[] and colind[].
= 0: Zero-based (C style) indexing: Starting index is 0.
= 1: One-based (Fortran style) indexing: Starting index is 1.
[out]val2[]Array val2[lval2] (lval2 >= nnz)
Values of nonzero elements of output matrix.
[out]colptr2[]Array colptr2[lcolptr2] (lcolptr2 >= n + 1)
Column pointers of output matrix.
[out]rowind2[]Array rowind2[lrowind2] (lrowind2 >= nnz)
Row indices of output matrix.
[in]base2Indexing of rowind2[] and colptr2[].
= 0: Zero-based (C style) indexing: Starting index is 0.
= 1: One-based (Fortran style) indexing: Starting index is 1.
[out]info= 0: Successful exit.
= i < 0: The (-i)-th argument is invalid.
