structfun(). If the results are scalar numeric values and what you want is an array of the results, then do not use the 'uniform', 0 option. Otherwise use 'uniform', 0, which will cause a struct to be returned with fields the same as the original field names, but with content as generated by the function you specified.
Example:
structfun(@mean2, data) %mean2 always returns a scalar even for empty input
structfun(@tan, data, 'uniform', 0) %returns struct with fields ID0 and ID1 in which each value has been replaced by its tan.
