Void procedures

In some cases the routine of ALIAS-C++ have procedure arguments that are useless. ALIAS-C++ proposes void procedures that may be used as such argument and have no effect on the calculation:

• int ALIAS_Simp_Proc_Void: a simplification procedure that always return 0
• INTERVAL_MATRIX ALIAS_Gradient_Void(int l1,int l2,INTERVAL_VECTOR &P): a gradient procedure that returns a not defined interval matrix
• int ALIAS_Matrix_Void(INTERVAL_VECTOR &Box,INTERVAL_MATRIX &P): a procedure that may be used for routine asking for a matrix but the return code is 0, stating that the matrix has not been computed
• INTERVAL_MATRIX Hessian_Void(int i1, int i2, INTERVAL_VECTOR &X): a procedure that returns an empty (1,1) interval matrix
• void Compute_Gradient_Non_Linear_Void(INTERVAL_VECTOR &X,INTERVAL_MATRIX &J): a procedure for the simplex algorithm that is empty
• INTERVAL_VECTOR ALIAS_Void_Update_Range(double z,INTERVAL_VECTOR &Input): a Range procedure for the continuation algorithm that just returns Input
