MATLAB: Cant get the code to work

Question

Hi, ive written the following function

function Guass_t=Gaussian_t(x)
    n = length(x);
    mean = sum(x)/n;
    std = sqrt(sum((x-mean).^2/n));
A=sqrt(2*pi*((std).^2));
B=1/A;
C=(x-mean).^2;
D=2*std*std;
Gauss_t= B*exp(-C/D)
end

It doesnt seem to work. It keeps saying Guass_t is undefined. Please can someone explain where I have gone wrong.

Answer 1

Note the spelling difference:

Guass_t    % function output arugment
Gauss_t    % variable defined in the function
