How do I define a function that evaluates in input

Currently been typing:

theta_Degree=40

theta=(theta_Degree*pi/180)

T = [cos(theta)^2 sin(theta)^2 2*cos(theta)*sin(theta); 

sin(theta)^2 cos(theta)^2 -2*cos(theta)*sin(theta);

-cos(theta)*sin(theta) cos(theta)*sin(theta) cos(theta)^2-sin(theta)^2]

But I'd like to simply type T(theta) from saved script but I can't seem to figure out how to.

[Birdman]

function y=T(theta_Degree)
theta=theta_Degree*pi/180;
y=[cos(theta)^2 sin(theta)^2 2*cos(theta)*sin(theta);sin(theta)^2 cos(theta)^2 -2*cos(theta)*sin(theta);-cos(theta)*sin(theta) cos(theta)*sin(theta) cos(theta)^2-sin(theta)^2];
end

Then type in command line

T(40)

and see the results.

Thank you very much! Just started learning Matlab and I appreciate the help.
