How can I make second struct with summary from the first struct?

I have struct s with 96 fields 21*21, how can I make new struct s_new with fields that conteins sumarry of each column of fields from s.

(s_new should be 96 filelds 1*21.)

And the same thing but with summary of rows(96 fieldsd 21*1).

s_new = structfun(@(field) sum(field,1), s, 'uniform', 0);

Change the sum to var or as required.
