Undefined function error in matlab

Question

function im = Thresholding(I)
[r,c] = size(I);
im = zeros(r, c);
for i = 1:r
for j = 1:c
    if I(i,j)> 105
        im(i,j) = 1;
    end
end
end
im = bwareopen(im, 5);
im = imfill(im, 'holes');
end

I'm trying to use this code and I got this error " Undefined function or method 'bwareopen' for input arguments of type 'double'"please help me

It seems that the program doesn't recognize it. Are you sure you have the proper version that contains a definition of the function? — Leb, Oct 04 '15 at 02:30

You're calling bwareopen but you should be calling bwareaopen. The latter has an extra a.

i also get this error " Thresholding at 2 [r,c] = size(I);" when i run the above code. can someone help me? – user5405704 Oct 04 '15 at 06:38
@user that is the stack where the error occurs, but not the error message. – Daniel Oct 04 '15 at 08:29
Input argument "I" is undefined. this is the error. i can't fix it yet – user5405704 Oct 04 '15 at 14:00

You have to call the function with an argument, not just hit the run button. – Daniel Oct 04 '15 at 14:58
