I have created a function to compute the Euler of a given IVP as seen below:
function U= Uler(N,h,y)
t = 0;
S = N/h;
for i=1:S
y = y +(h*(0.5*y*(1-y/2)))
t = t +h
end
U=y
end
My question is how do I plot a graph using the values of t and y I obtained during this function?

function [t,y]= Uler(N,h,y)
S = N/h;
y = zeros(1,S) ;
t = zeros(1,S) ;
% initial condition
y(1) = 0 ;
t(1) = 0 ;
for i=2:S
y(i) = y(i-1) +(h*(0.5*y*(1-y/2))) ;
t(i) = t(i-1) +h
end
end
[t,y]= Uler(N,h,y) ;
plot(t,y) ;

I've tried putting in this function, and I don't seem to be getting any results, it says Error: "File: Uler.m Line: 13 Column: 1 This statement is not inside any function. (It follows the END that terminates the definition of the function "Uler".)"
and even after putting that plot function before putting end, it still says there's an error on line 9.
