Please help me create simple function to convert celsius to fahrenheit and another for inverse?

Matlab keeps complaining about invalid syntax but I don't understand why. Errors keep arising mainly with the brackets saying they are missing but they are not, that there is a syntax error (it probably is) or it says a new line is needed between statements (why when I'm creating a function)?

At the moment I have a function>> function [F] = cel2fahr((C)*1.8+32)

of which celsius to fahrenheit is >> F = (C)*1.8+32;

I have tried it in this form >> function [F] = cel2fahr((9/5.*C)+32)

And with various combinations of brackets around the (C) in the formula and C in different places - I'm getting exasperated

I'd really appreciate any help

Declare it as:

function F = cel2fahr(C)

That should work.

See Function Basics (link) for details.
