how to calculate a mean of an cell array

• 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)

here the 3*6 matrix:

m =
          28         195          29         195          30         195
          28         194          29         194          30         194
          28         193          29         193          30         193

when i apply what you said here the result

mOY =
    28   195    29   195    30   195
    28   194    29   194    30   194
    28   193    29   193    30   193
i think you mean "mMean = mean(m, 1)

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.
