Plotting a Piecewise Function

Hi everyone, I'm very new to MATLAB. I'm having a trouble with plotting a piecewise function.

Here is my piecewise function:

y(x)=if x<0, y=0

if x>0, y=1

z(x)=(1+(x-1).*exp(-x))*y(x)

I need to plot z(x) function. Here is my code:

x=-3:0.01:3;

syms x

y=piecewise(x<0,0, x>0,1);

z=(1+(x-1).*exp(-x))*y(x);

plot(z,x)

And this is the error that I got: Error using plot Data must be numeric, datetime, duration or an array convertible to double.

Thanks in advance.

syms x z(x)
y=piecewise(x<0,0, x>0,1);
z(x)=(1+(x-1).*exp(-x)).*y;
fplot(z,[-3 3])

Thank you so much.
