Substitution problem of function from one variable to another variable

Hey guys, thanks for your valuable time to take a look at this problem

I am quite new in MATLAB, so please forgive me for silly question, thanks a lot =))

Problem:

I got a function x and y, ie f(x,y) = x+y+1

Now I need to use matlab to help me sub x to become i and y to become j, ie f(x,y)-->f(i,j)==i+j+1

Is that possible to use command 'subs' or any other solutions for this problem?

Thanks in advanced !!!

First define your function:

>> fun = @(x,y) x+y+1;

Now call the function with any values that you like:

>> fun(1,2)
ans = 4

You can even pass variables to it:

>> a = 3;
>> b = 2;
>> fun(a,b)
ans = 6
