I copied data into a new variable called X, inwhich inside X there are 1851x1 array. Inside each array there are several number of data of array inside all 1851x1 array. How can I find the mean of each 1851 data. Thanks very much

Did you try the obvious brute force for loop method:
theMeans = zeros(numel(X), 1);
for k = 1 : numel(X)
% Get the mean of the 1851 element double vector that is
% inside the kth cell of the X cell array.
theMeans(k) = mean(X{k});
end

cellfun(@mean,--) applies the mean function to each cell of the cell array and returns a numeric array containing the mean for each cell.
