can u explain the logic of this program.while am running the program i got the error like this"Error using alphatrim (line 3) Not enough input arguments.""can u suggest the solution

function f = alphatrim(g,m,n,d)
% implements a alpha-trimmed mean filter.
inclass = class(g);
g = im2double(g);
f = ordfilt2(g,1,ones(m,n),'symmetric');
for k = 1:d/2
    f = imsubstract(f,ordfilt2(g,k,ones(m,n),'symmetric'));
end
for k = (m*n + (d/2) + 1):m*n
    f = imsubstract(f,ordfilt2(g,k,ones(m,n),'symmetric'));
end
f = f/(m*n - d);
f = changeclass(inclass,f);

Kindly format the code while posting using the {}Code button at the top of the window you type in.

As to the error you get, did you run the script from the editor using the play button or pressing f5? In that case the input arguments(i.e., g,m,n,d) are not passed to the function.

You have to run it from your command window by calling

   f = alphatrim(g,m,n,d)

after specifying the values for g,m,n and d.

As the error mentions, please check you input arguments, g,m,n,d.
