I am trying to insert a function into my program but every time it tells me "error in perimeter line 3, p=4*s". Here is part of my program as well as my function. Can someone tell me what I am doing wrong? Thanks
function p=perimeter(s);
p=4*s;
end
into this part of my program:
h=input('What shape do you want?:','s');
if strcmp(h, 'square')
s=input('The length of a side is (m):');
A=s^2;
p=perimeter;
fprintf('The area of the Square is %.2f meters^2 \n',A)
fprintf('and the perimeter is %.2f meters\n',p)

You need to pass s into your perimeter function:
p = perimeter(s);
