I am supposed to write a function that accepts temperature in degrees Fahrenheit(°F) and returns the corresponding value in degrees Celsius (°C). Here is my code:
function [Celsius] = TemperatureConversion(Fahrenheit)
Celsius = (5/9)*(Fahrenheit-32);
When I run this code, I get this:
>> TemperatureConversion
Not enough input arguments.
Error in TemperatureConversion (line 12)
Celsius = (5/9)*(Fahrenheit-32);
Why am I getting this error?

Error in TemperatureConversion (line 12)
Why does the error message say line 12? You showed us two lines of code: this tells us that the code you have shown us is not the complete code in the file that you are trying to run, so we have no idea what you are actually trying to do.

You should save the function in a m file and then call it from command line as:
fah=77;
degree=TemperatureConversion(fah)
You need to read this documentation carefully.

Ohhhhh my, I get it now.
>> TemperatureConversion(50)
ans =

I needed to pass the input argument like Birdman said! Thank you guys

You are welcome. These are very basic concepts, learn them well to proceed well.
