Mean Value in cell array MATLAB

I have generated a cell array of 1x5 cells with a 10x1 column vector on each cell.

How can I find the average of all the column vectors? So to have a final 10x1 new column vector that contains the means. Thank you

Solution

  • I would concatenate the cell array contents along the second dimension (using cat and {:} indexing to get a comma separated list) and then take the mean along this first dimension

    result = mean(cat(2, data{:}));

    Since your data is purely numeric, you should avoid cell arrays and instead deal with a 5 x 10 matrix as that will be much more performant. You can easily create that the same way we did above.

    matrix_data = cat(2, data{:});
