PURPOSECreate_SuperNode_Matrix() creates a SuperMatrix in supernodal format.
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 that contains the nonzero values of the
matrix, packed by column.
int *nzval_colptr (input)
pointer to array of beginning of columns in nzval[]
int *rowind (input)
pointer to array of compressed row indices of rectangular
supernodes
int *rowind_colptr (input)
pointer to array of beginning of columns in rowind[]
int *col_to_sup (input)
col_to_sup[j] is the supernode number to which column j
belongs; mapping from column to supernode number.
int *sup_to_col (input)
sup_to_col[s] points to the start of the s-th supernode; map‐
ping from supernode number to column.
Stype_t stype (input)
stype = SLU_SC, which specifies the column-wise, supernode
storage structure to be created.
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.
