Standard deviation of multiple cell arrays

I've figured out how to get the average of multiple cell arrays. M is a 1x19 cell
MEAN = mean(cat(3,M{:}),3)
This works well. Now I want to apply the same for the standard deviation:
SD= std(cat(3,M{:}),3)
However, the following error occurs:
>> SD= std(cat(3,M{:}),3)
Error using var (line 197)
W must be a vector of nonnegative weights, or a scalar 0 or 1.
Error in std (line 59)
y = sqrt(var(varargin{:}));
Could someone help me how to rewrite the code?
Thanks and best regards,
Christoph

I am not certain what ‘M’ actually is.
Try this —
M = {rand(5),rand(5),rand(5)} % Create 'M'
SD = std(cat(3,M{:}),[],3)
Supply an empty array [] for the weight argument and it should work.
