- i have a 3*6 matrix
m=[pc oc rc;
yc centroid ic;
ec uc hc]
- where each value (pc, or...) define x,y coordonates of a pixel, then i converted this matrix to an cell array with :
c=mat2cell(m,ones(1,size(m,1)),2*ones(1,size(m,2)/2))
- here i want to calcule a mean of this cell array:*
A=[mean(reshape(cell2mat(c), [2, 3, 3]), 3)]
- but the result is not that one i want :(, i want to know where the problem is and how can i correct it

Why are you using cell arrays? Why not just take the mean of m before doing any cell array stuff? Make m a 3D array instead of a cell array if you have multiple copies of m, then take the mean.
mMean = mean(m, 3)

I wasn't really sure what numbers you wanted to include in the mean. Like if it's the mean of the rows, mean of the columns, or mean of the whole m array. I still don't know. But I know it will be easier if you avoid cells and just use regular numerical arrays, even if you have to use a third dimension.
