Hello,
when i write this code in matlab it only gives me the value for the Area A and not the circumference C. What did I do wrong? Thanks
function [A,C]= myfunction(radius)
radius=2.45;
A=pi*(radius^2);
C=2*pi*radius;
end

When you called it did you call it with two output arguments? e.g.
radius = 5
[A,C] = myfunction(radius)
Also, you reassign the radius a value of 2.45 inside of the function, so it will not actually use the value of the radius supplied as an argument. I assume that this is not what you intended

Hello, yes I used two output arguments, [A,C]. I just have these two equations (area and circumference) and I'd like to add them to a function.
When I do this
radius=2.45;
function [A,C]= myfunction(radius)
A=pi*(radius^2);
C=2*pi*radius;
end
it tells me 'Local function name must be different from the script name'. I'm guessing it's because i've put the radius before the function.
Maybe what i'm looking for is not available in matlab?

You have to put this part into a separate file and save it as myfunction.m
function [A,C]= myfunction(radius)
A=pi*(radius^2);
C=2*pi*radius;
end
Then from the command line you can type
>radius = 2.45
>[A,C] = myfunction(radius)
