if and switch statement

I have 2 sets of code below. One is with an if statement, and the other is with a switch statement.

code 1 is fine, but for code 2, I wanted to practice doing this code with a switch instead of if.

for code 2, I want the range of the input to be anthing from 1 to 50, so then I would have

case {1,2,3,4,5,6,7.8,9,10,11...50} 

etc, is there a simply way to write this. As writing 1 to 50 is inefficient.

Hope my question makes sense!

% Code 1 if 
clc, clear all, close all

c = 331;

temp = input('Enter temp value: ');
if temp < 0 || temp > 50
    disp('Error in temperature value, enter a value in the range of 0 to 50')
else 
    speed = c+0.6*temp;
    fprintf('\nThe speed is %.1f\n\n', speed);
end




% code 2 switch
clc, clear all,close all

c = 331;
temp = input('Temperature in celsius: ');

switch temp
    case {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20} % I gave up after 20....
        speed = c*331*0.6*temp;
        fprintf('Speed is %.2f\n\n',speed)
    otherwise
        disp('Error in temperature value, enter a value in the range of 0 to 50')
end

To answer your question, you would use

case num2cell(1:50)

But a switch/case is not the optimal method in this context. What if the user entered 22.5? 22.5 does not match any of the values 1:50.

A conditional statement would be much better not only because it avoids the problem above but it's more efficient than a switch/case.

if temp >= 1 && temp <= 50

Even if you only want positive integers,

if temp >= 1 && temp <= 50 && mod(temp,1)==0
