Hi everyone, I have a problem in finding an integral of a function. I'm given the following function: x(t) = t + 1 (-1 <= t < o ); e^-t (0<= t <= 2); 0 (otherwise).I have to find the integral and plot it with its derivative and the given function.
Here is my code:
%Set up integral vector
u(1:1000) = 0;
%Find the integral
for n = 1:999;
if( (t(n)>= -1) & (t(n)<0) );
u(n) = 0.5.*(t.^2) + t;
end
if ( (t(n)>=0) & (t(n)<2) );
u(n) = -1.*(exp(-t));
end
if( (t(n)>2 ) )
u(n) = 1.*t;
end
end
subplot(3,1,3);
plot(t,u);
I get the following error when trying to run the code:
? In an assignment A(I) = B, the number of elements in B and
I must be the same.

u(n) = 0.5.*(t.^2) + t;
