Plotting output for a range of numbers

Hello,

It's been a while since I've used MATLAB on a daily basis and I'm having trouble with plotting the response of a system over a time interval depending on whether the time is less than or greater than a value.

My time interval is from 0 to 10 seconds with 0.1 second intervals. If t is less than 3 seconds I have one equation and if t is equal to or less than 3 I have a second equation. Any help would be greatly appreciated.

t = 0 : 0.1 : 10;
for i = 1:numel(t)
if t(i)<=3

% eq1
eq1(i)=t(i).^2;  %example
elseif

%eq2
eq2(i)=t(i).^3; %example
end
end

plot(t(1:numel(eq1)),eq1,'r')

hold on

plot(t(1:numel(eq2)),eq2,'m')
