(1:10).^((1:3)')

or on older MATLAB

bsxfun(@power,1:10,(1:3)')

Rather than sweating out a vectorization, it's a lot easier to do it with a single for-loop. Also it may be just as fast or faster.

 n = 4;
 m = 21;
 std_t = zeros(m,size(pc,2));
 for k = 1:m
  std_t(k,:) = std(pc(k:k+n-1,:)-repmat(MA(k,:),n,1),1);
 end

The rows of 'std_t' are your vectors std_t1, vtd_t2, etc. Make sure 'pc' is defined up to m+n-1 rows.
