hi i want use for loop in mathematica but i do not know what is the role of i++? i think this loop is equal to for i=1:4 print(i) end in matlab. Do I understand correctly? For[i = 0, i < 4, i++, Print[i]]
See my comment to your other question:
i++ increments i by 1 each time.
This is the same as For[i = 0, i < 4, i=i+1, Print[i]]
For[i = 0, i < 4, i=i+1/4, Print[i]] increments i by 1/4 each time, similar to Matlab for i=1:1/4:4 print(i) end
