How do I measure mean of every 10 data of a vector size 1x1500?

I have a vector of size 1x1500, whose every 10 values, are of one person (i.e, there are 150 persons).

I should estimate the mean of those 10 values for each person. my script is not working well, any idea?

Answer 1

[David Sanchez]

A = rand(1,1500); % your data
M = zeros(1,150); % MEAN MATRIX
for k=1:150
    M(k) = mean(A(((k-1)*10+k):10*k));
end

Thanks David!

Avoiding loops , try:

A = rand(1,1500); % your data

M = mean( reshape( A, 10, 150 ) );

Perfect, this works completely accurate.

% DATA
  A = rand(1,1500) ;
  N = 10 ;

% ENGINE
  M = accumarray((floor((0:numel(A)-1)/N)+1).',A(:),[],@mean) ;

% CHECK
  k = 17 ;
  isequal(M(k),mean(A(((k-1)*N)+(1:10))))
