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. Error in ==> tut1 at 32 u(n) = 0.5.*(t.^2) + t;

i have 1 question
how do i apply 1/s in simulink block to Mcode, for example Xdot to X in simulink, we just apply the 1/s(integration block). so i just want to know, is it possible to integrate the Xdot to X in m code??
