python - Create a "counter" on matlab from 0:limit-1. The length of counter is not determined in the program -

q- create "counter" 0:limit-1 (for example if choose 3 display 0,1,2). length of counter not determined in program , should determined when being run , inputs can differ each other

this solution on python want compute on matlab. how do that?

for in range(3):     print(3-i) s in range(3,-1,-1)     print s 

so answer :

3 2 1 3 2 1 0 

as dan hinted in comments above, the colon operator of matlab want.

here examples corresponding python example:

using bare colon operator:

3:-1:0 

gives

ans =      3     2     1     0 

which 1 4 row vector.

you'll same result with:

limit = 3; limit:-1:0 

---

if want use basis loop:

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

will output:

 3  2  1  0 

---

more do:

istart = 6; istep = -2; iend = 0;  = istart:istep:iend     disp(i) end 

which gives:

 6  4  2  0
