function needs to return multiple outputs but only returns one, leads to incorrect plot

I'm new to matlab and having trouble plotting a solution to a differential equation. The task is to use Euler's Method to reach and answer, as well as solving directly, then overlaying the two solutions on one plot. I was able to plot Euler's correctly, but my direct solution doesn't work because instead of returning one output(y) for each input(t) it only returns a single output(y(t_last))

%Euler's method
t=zeros(51,1);
y1=zeros(51,1);
t(1)=0;
y1(1)=200;
for i=1:50
    t(i+1)=t(i)+.5;
    y1(i+1)=y1(i)+.01.*(.65*(1-((y1(i)/(5.4))))).*y1(i);
end 

%direct solution
y2=zeros(51,1);
y2(1)= 200;
y2= (-1.03*5.4*exp(1).^(.65*t))/(1-1.03*exp(1).^(.65*t));

%plot
plot(t,y1,t,y2)

Nothing I do seems to work, please help! Note: the direct solution plot leads to the correct answer but only for the last value of t. all other points of t do not follow the right trend.

If your function returns more than one output, you have to ask for as many of them as you need in your calling code.

Example —

Function definition:

function [t,y] = myFunction(a,b)
...
end

Function call:

[T,Y] = myFunction(A,B);

Also, you need to vectorize ‘y2’ to get the result you probably want:

y2= (-1.03*5.4*exp(0.65*t))./(1-1.03*exp(0.65*t));
