h=0.1;
y=1;
t=0;
Tend=4;
i=1;
while(t(i)<Tend)
t(i+1)=t(i)+h;
slope=(5*exp(-2*t)-3*exp(-4*t))/2;
y(i+1)=y(1)+slope*h;
end
Can anyone help me figure out whats causing the error in my code? I am trying to numerically approximate a function value from 0 to 4 seconds with a 0.1 secnd time step.

You should proceed something like this:
h=0.1;
Tend=4;
t = 0:h:Tend ;
y = zeros(length(t),1) ;
y(1) = 1 ;
for i = 1:length(t)-1
slope=(5*exp(-2*t(i))-3*exp(-4*t(i)))/2;
y(i+1)=y(i)+slope*h;
end
plot(t,y)
