MATLAB: Average

Question

i have a 42*16384. how do i average it so that i get a new matrix of size 42*2048 (if N=2048 represents one revolution and N=16384 represents 8 revolutions).

Answer 1

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)) ;
