How can i pick a speed based on a "n" value.


Let's say my n= 13 i want to get the value 30km/h for V, but if its 8 i want 60km/h.
I have tried with for/while/if. But im guessing im doing something wrong or i don't know what to write exactly.


Any help is much apprecite it!

Thank you for the answer, but this doesn't help me. Or i don't understand it .

Example, i have N=10, based on N i want to get V. V for N=10 it's from here:
, but if i change N to 9 i want to obtain V=30km/hr.
Thing is i have 8 variable based on N, and i want to obtain the values only by changing N.


Sorry if i don't explain very well.

The procedure is to get a vector of the potential values which can then be accessed by index.
You also could implement it as a function v(n) = 30 + mod(n-1, 4)*10

Great it works now. I just have to figure it out how to implement it for the rest of the file .
Thank you very much!

How would you tackle this one?

Divide n by 2, a bit of rounding and offset adjustment should do the job.

I can't seem to get it to work, and for next examples i need to match it with a list that has some randomnes in number list. Isn't there a way i can create a list of number and if my "n" matches that list then i can get the correct value? I tried with for, if and so on. but im still a newbie in Smath.

Thank you once again!

If you have a limited set of choiches, this might be a solution.



Also, I think Martin has a point, since these "n" values should come from some formula.

If there is no rule, then you have to provide a vector with values and adress it with index n. A simple lookup table by index. Fill the vector by hand, by reading a file or asking a chatbot.

This works but i have other areas with diferent increment and i can't control them with interval. I will list a few of them:

here is 1,2,3 then goes to 16,17,18 then 26,27,28.

So i have this interval from the picture above and the one before with "Latimea benzii".

Found a not very fancy solution, but it works .
