sym_get_matrix

int sym_get_matrix(sym_environment *env, int *nz, int *matbeg, int *matind, 
		   double *matval)

Description:
This routine is used to get the constraint matrix in a standard column-ordered format.
Arguments:

sym_environment *env IN Pointer to the SYMPHONY environment.
int *nz OUT Pointer to integer indicating the non zero elements of the constraint matrix.
int *matbeg OUT Pointer to a double type array to be filled by the starting positions of each of column. Note that, the size of this array has to be at least the number of columns+1
int *matind OUT Pointer to a double type array to be filled by the row indices corresponding to each entry of matval. Note that, the size of this array has to be at least the number of nonzero elements of the constraint matrix.
int *matval OUT Pointer to a double type array of the values of nonzero entries of the constraint matrix in column order. Note that, the size of this array has to be at least the number of nonzero elements of the constraint matrix.
Return values:
FUNCTION_TERMINATED_ABNORMALLY Function invoked unsuccessfully.
FUNCTION_TERMINATED_NORMALLY Function invoked successfully.
