data - your array [42x16384]
EDIT
out = mean(reshape(data,size(data,1),[],8),3);
eg:
data - your array [55x72000]
out = mean(reshape(data,size(data,1),[],3),3);
or
out = squeeze(mean(reshape(data,size(data,1),3,[]),2)) ;

I am still getting the same error message with
out = squeeze(mean(reshape(data.',size(data,2),8,[]),2)).'
