I'm trying to input a data set to calculate the Gaussian (Normal) Distribution. This something that i found on youtube but I keep getting the error: Error in my_gaussian (line 4) f = zeros(n, 1); When i hit Run. What is this error about ?

function [ X, f ] = my_gaussian( mu, sigma_sq, min_x, max_x, n)

f = zeros(n, 1);

X = zeros(n, 1);

x = min_x;

dx = (min_x - max_x)/n;

for i = 1:n

X(i) = x;

f(i) = 1/ sqrt(2*pi*sigma_sq) * exp( -(x - mu)^2 / (2 * sigma_sq) );

x = x + dx

end

How is Matlab supposed to know the input values? If you hit the green run button you execute the function without any inputs.

You need to run this function with inputs.
