Plot with smaller variation in input argument under user defined function?

I am stuck with a smaller concept that How to Plot with smaller variation in input argument under user defined function?

For example I have a function:

function ques(x,del_x)
xx = x+del_x;
t = sin(xx);
plot(xx,t,'-');
end

my input has 2 aruguments with values

x = -pi:pi/100:pi;
del_x = eps/pi;

First of all I want to plot x and del_x =0 then on the same plot (window) I want x and del_x mentioned above. hold on is not working when I execute this code with different values in command window.

Looking for help.

Thanks

"hold on is not working when I execute this code": It's probably because the the value of del_x is very small and it is difficult to see the impact. Try changing the value of del_x to higher values and then you can see that "hold on" works properly.

>> x = -pi:pi/100:pi;
>> del_x = pi/2;
>> ques(x,0)
>> hold on
>> ques(x,del_x)
