Hi!
Suppose R = C = 1 then the transfer function from the input voltage to the voltage across the capacitor is 1/ (s+1). So Vc(S) / V(S) = 1/(s+1). Getting back to time-domain: Vc(t) = V(t) * e^-t. What's wrong here? It should have been V(t) ( 1 - e^-t ).
The rising function is step( transfer_function ) and the decaying one is ezplot ( ilaplace ( transfer_function )). Why are these two not the same?

Thank you!

What does the circuit look like?
Where are you measuring the output voltage?
