Hi I foun this ‘extract’ of a matlab code on the internet. Can someone explain to me line by line whats happening? Im REALLY in need of help.

***

% ————- % This is code to make the edge detecting filter % —-%

function filter=gaussfilt(N)

% calculate alpha so the filter fills all N points

alpha=N;

first=-(1-N/2)*exp(-(1-N/2)^2/alpha);

count=0;

while first<.1*(-(1530/4000*N-N/2)*exp(-(1530/4000*N-N/2)^2/alpha))

count=count+1;

alpha=N*500*count;

first=-(1-N/2)*exp(-(1-N/2)^2/alpha);

end

for n=1:N

filter(n)=-(n-N/2)*exp(-(n-N/2)^2/alpha); % d/dt of a gaussian

end

filter=filter/sum(abs(filter)); % normalization
