PURPOSE
Create_CompCol_Matrix() creates a SuperMatrix in compressed column for-
mat.
ARGUMENTS
SuperMatrix *A (output)
On exit, A holds an allocated matrix as well as all the
describing elements of the structure object.
int m (input)
m specifies the number of rows of the matrix to be created.
int n (input)
n specifies the number of columns of the matrix to be cre-
ated.
int nnz (input)
nnz specifies the number of nonzeros of the matrix to be cre-
ated.
float *nzval (input)
nzval is an array of length nnz (or greater) that contains
the nonzero values of the matrix, packed by column.
int *rowind (input)
rowind points to the array of row indices of the nonzero val-
ues.
int *colptr (input)
colptr is a pointer to the array of column start indices in
nzval[] and rowind[].
Stype_t stype (input)
stype specifies the storage structure of the matrix to be
created.
stype = SLU_NC
Dtype_t dtype (input)
dtype specifies the data type of the matrix to be created.
Mtype_t mtype (input)
mtype specifies the mathematical property of the matrix to be
created.
NOTES
To destroy the data structure in SuperMatrix A that was created by Cre-
ate_CompCol_Matrix, the user may call Destroy_CompCol_Matrix() or
Destroy_SuperMatrix_Store(). The former will attempt to deallocate the
three arrays that Create_CompCol_Matrix requires on input. If this is
not desirable, the user may call Destroy_SuperMatrix_Store() which
deallocates only the data structure that Create_CompCol_Matrix itself
has allocated.
