undefined function 'piecewise' for input arguments of type 'double'.

Trying to run this piecewise function:

x = [-5:0.1:5];
y = piecewise(x <= 1, ((-2.*(x.^2))+9.*x-7), double(x) > 1, ((10.*sqrt(x))+3));
plot (x,y);

but it gives the following error: "Undefined function 'piecewise' for input arguments of type 'double'."

any fixes please?

thanks in aniticipation.

syms x
y = piecewise(x <= 1, ((-2.*(x.^2))+9.*x-7), x > 1, ((10.*sqrt(x))+3));
fplot (x,y,[-5 5])
