MATLAB: ()-indexing must appear last in an index expression

indexingmean

I have a 70x70x328 matrix and want to take the mean along either the first or second dimension (they're the same) while ignoring elements that are 0. I'm getting the error: ()-indexing must appear last in an index expression but don't know how to rearrange or what to add to my expression. Here's what I have

for i=1:length(files)
    Mean1(:,i)=mean(All_files(:,:,i)(All_files(:,:,i)~=0),2);
end

Thanks!

EDIT

Mean1 = squeeze(sum(data)./sum(data~=0))%first dimension  
Mean2 = squeeze(sum(data,2)./sum(data~=0,2))%second dimension

"dim" is the first array dimension of the multidimensional array x whose size does not equal 1.

MATLAB: How to compute Kurtosis

if you have stats toolbox, there is a function called kurtosis. Even otherwise, this should be very straightforward.

function k = kurtosis3(x,dim)
% Kurtosis function
mu = mean(x,dim);
repsiz = ones(1,length(size(mu)));
repsiz(dim) = size(x,dim);
d = (x-repmat(mu,repsiz)).^2;
n = d.^2;
k = mean(n,dim)./(mean(d,dim)).^2;
