Unformatted text preview: x ( t ) = ± 2 e t +1-1 ≤ t ≤ 3 else Attach the plot and your matlab code to your homework. Hint: Create a vector whose values are samples of x ( t ) spaced closely enough so you get a smooth plot. Then plot the vector against another vector which contains the time values at which these samples were evaluated. Problem 7: Let y ( t ) = e-2 t . (a) Use matlab to numerically compute the integral Z ∞-∞ x ( t ) y ( t ) dt where x ( t ) is as in Problem 6. (b) Also compute the integral analytically, and compare with the result in (a)....
