I would recommend some matlab tutorial, since this is very basic. However:

% make z from -5 to 5 with steps of 0.01
z = -5:0.01:5
% create the function
f = (1 / (sqrt(2*pi))) * exp(- z.^2 / 2)
% plot the function
plot(z,f)
% label your axes
xlabel('z')
ylabel('frequency')

you can change parameters to see how this will change. Also, in gaussian distribution, there is another important parameter named sigma. you can add it to the code and see how the curve will change.

good luck with that.

srate=0.01;

z=-5:srate:5;

Exp_comp = -z.^2/2;

GL = exp(-z.^2)/2;

figure,plot(z,GL),xlabel(' frequency');ylabel(' z');
