How to make an array of function outputs?

%equation for y
yFunction = @(t) ((4.*t.^3)+(3.*t.^2)+(5.*t)+5);
%Plotting the function
fplot(yFunction,[-10,10]);
I am trying to find the minimum and maximum values of this function and I was wondering if there is a way to make an array of the outputs from the function. Then, with the array I can find the min and max values.
Cheers!

If your equations will always be polynomials, then
p=poly([4,3,5,5]);
d=polyder(p);
r=roots(d);
x=polyval(p,r);
relative_min=min(x);
relative_max=max(x);
