mean of cells in loop with different dimensions

I have a loop, and creat B{i,1} on it. now I need to calculate the mean of each cell.i used meanOfCities(i)= mean(cell2mat(B(i,1))) ; it workes just for 4 loop, and then this error : Index exceeds matrix dimensions. will occure.

Inside the loop, right after you assigned B{i, 1} take the mean and assign that to a vector:

cellContents = B{i, 1}; % A vector, matrix, or higher dimensional array - whatever it is...
theMeans(i) = mean(cellContents(:));

Now, after your loop, theMeans will be the mean of every cell that you've assigned.

I need the loop, I have different i=1:9. how it workes without the loop? there is just one loop that I make B{i, 1} on it and then get mean

Without the loop, it really depends on what is in the cells. If all the cells contain the same size matrix you might be able to just use cell2mat() and then use mean().
