simulink - Mathematical modelling in Matlab -

-

i new matlab , need perform simple task. have input function u(t)=2t-1 , output function

y(t)=(-4/45)e^3t+ (1/5)e^(-2t)-1/3t-1/9

i have find corresponding behavior model, defined via transfer function , simulate behavior model in matlab/simulink. not sure approach should use. have done far transferred input , output function in s-domain , calculated transfer function. mean simulate behavior model in matlab? can please me? beginner. thank much!

if you've done laplace transform , calculated transfer function in s-domain, think means applying transfer function arbitrary transient input , calculating response.

the transfer function based on response due unit step function.

if have input other unit step function (e.g. sinusoid), you'd calculate response follows:

  1. transform arbitrary input function s-space.
  2. multiply transfer function response in s-space.
  3. transform response in s-space time domain.

this how laplace transforms work.

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
