So I'm not going to lie, I'm pretty new with this software. I was assign a homework assignment, but I'm not sure how you graph a step function. Given this waveform use the step function to find an equation: http://img163.imageshack.us/img163/2545/stepfunction.jpg" [Broken] I calculated the step function to be: x(t) = (t^2)[u(t)-u(t-2)]+2(t-4)[u(t-2)-u(t-4)] , which I'm pretty positive is right. Now graphing in Matlab is my biggest problem. I've looked over my textbook at sample graphing techniques, this is what I have attempted. Code (Text): >> x = inline('(t^2)(u(t)-u(t-2))+2(t-4)(u(t-2)-u(t-4))', 't') g = Inline function: g(t) = (t^2)(u(t)-u(t-2))+2(t-4)(u(t-2)-u(t-4)) >> t = (-1:5); >> plot(t,g(t)); [COLOR="Red"]??? Error using ==> inlineeval at 15 Error in inline expression ==> (t^2)(u(t)-u(t-2))+2(t-4)(u(t-2)-u(t-4)) Error: Unbalanced or unexpected parenthesis or bracket. Error in ==> inline.subsref at 27 INLINE_OUT_ = inlineeval(INLINE_INPUTS_, INLINE_OBJ_.inputExpr, INLINE_OBJ_.expr);[/COLOR] Any tips or suggestions would be helpful, thank you.
