lu_int basiclu_obj_initialize ( struct basiclu_object *obj, lu_int m ); /* Purpose: Initialize a BASICLU object. When m is positive, then *obj is initialized to process matrices of dimension m. When m is zero, then *obj is initialized to a "null" object, which cannot be used for factorization, but can be passed to basiclu_obj_free(). This routine must be called once before passing obj to any other basiclu_obj_ routine. When obj is initialized to a null object, then the routine can be called again to reinitialize obj. Return: BASICLU_OK *obj successfully initialized. BASICLU_ERROR_argument_missing obj is NULL. BASICLU_ERROR_invalid_argument m is negative. BASICLU_ERROR_out_of_memory insufficient memory to initialize object. Arguments: struct basiclu_object *obj Pointer to the object to be initialized. lu_int m The dimension of matrices which can be processed, or 0. */
