MATLAB: 3D image stack; determine mean of individual arrays; error code

3d image stackMATLABmean

Hi,I have a 1000x1000x1952 uint8 3D image array (Array), and would like to get the mean value of each individual array "image" and subsequently put these in a 1952×1 array (meanArray).
The code I use is:
meanArray= mean(Array,[1 2])
the error code I get is: Error using sum "Dimension argument must be a positive integer scalar within indexing range. Error in mean (line 87) y = sum(x,dim,flag);"
What am I missing here? Thanks! Barry

For some reason, mean was not written to let you operate along multiple dimensions in the same call. One alternative is to use sepblockfun (Download).
[m,n,p]=size(Array);
meanArray = sepblockfun(Array, [m,n,1], 'mean');
