I am working on a function where a user with no prior coding experience should be able to input a series of numbers to define my variables. The variables must be between 1 and 30 and must be an integer.
I currently have preventions to stop numbers outside of 1 and 30 (using logic) and another to stop decimals (using round(Var)).
The last prevention I am looking for is stopping the user from inputing words or letters. Ex: Var=q
I appreciate any help.
Fxn(20) %Input must be between 1 and 30; cannot be a word or letter
function output=Fxn(x)
x=round(x)
if x<1 | x>30
disp("Variable must be between 1 and 30")
return
else
Matrix=zeros(1,x)
end
end

Should the user be able to input the series of numbers in one go? Or should they always provide a scalar?
How are you getting your data from the user?
You don't define your output variable in your function, it doesn't deal with array inputs, and it is missing documentation.

Hello,
From my understanding, you want to check if the given input is a string or not.
You may consider using these functions in your code.
