Conversion to double from sym is not possible

My problem is I want to find the transfer function of a characteristic equation, then take the inverse laplace of it to get y(t)= blah. Once I have y(t) I want to graph, but I get the "Conversion to double from sym is not possible." error

%RC Circuit Lowpass Filter (voltage across capacitor)

%Resistance (Ohms), Capacitance (Farads) inputs R=100*10^3; C=100*10^-6;

%Voltage value of input A=5;

%System transfer function syms s trans=A/(R*C*s+1)

%Equation eq=ilaplace(trans)

%Time Domain Graph values for copying to Excel time=0:0.1:100; figure(1) plot(time,eq) hold on

In the Symbolic Math Toolbox, it’s more convenient to use ezplot. Replace your plot call with:

ezplot(eq, [0, 100])
