# How to get Taylor polynomial for functions?

I'm looking to write a program where i can input a function, like exp(x) or sin(x), and have the program return the Taylor polynomials for the function.
This is what I have so far. I am fairly new to Matlab and am still getting used to the software.
str=input('Function? ','s');
T=taylor(s);
sympref('PolynomialDisplayStyle','ascend');
disp T

You can use a function that is in the MAThWORKS fileexchange (I put the link):
str=input('Function? ','s'); %tray with: cos(x)
% https://la.mathworks.com/matlabcentral/fileexchange/67519-str2syms-symstr
z = str2syms(str)
T=taylor(z)
%
T =
x^4/24 - x^2/2 + 1
