Create A "counter" On Matlab From 0:limit-1. The Length Of Counter Is Not Determined In The Program

Q- Create a 'counter' from 0:limit-1 (for example if you choose 3 it will display 0,1,2). The length of counter is not determined in the program and it should be determined when it

Solution 1:

As Dan hinted you in the comments above, the colon operator of Matlab already do what you want.

Here are examples corresponding to your Python example:

Using the bare colon operator:

3:-1:0

gives

ans =
     3     2     1     0

which is a 1 by 4 row vector.

You'll get the same result with:

limit = 3;
limit:-1:0

---

If you want to use this as a basis for a loop:

limit = 3;
for i = limit:-1:0
    disp(i)
end

will output:

 3
 2
 1
 0

---

More generally you could do:

istart = 6;
istep = -2;
iend = 0;

for i = istart:istep:iend
    disp(i)
end

which gives:

 6
 4
 2
 0
