Hello,

I have 'fun1.m'

function fun1(x,y)
disp(x+y);

I have 'fun2.m'

function fun2(x2,y2)
disp(x2-y2);

Then I have a m-file

clear; clc;
funList = {'fun1','fun2'};
disp('1] fun1(x,y)     2] fun2(x2,y2)');
choice = input('Select function [1/2] : ');
funstr = str2mat(funList(choice));
hnd = str2func(funstr);
var1 = input('Input 1st parameter : ');
var2 = input('Input 2nd parameter : ');
hnd(var1,var2);
