I am trying to vectorise a matrix of by using the data:
Then I want to produce a 2x16 matrix where by
TEMP = [AN(1,3:3:end)-AN(1,1:3:end),AN(2,3:3:end)-AN(2,1:3:end);AN(1,2:3:end)-AN(1,1:3:end),AN(2,2:3:end)-AN(2,1:3:end)]
gives me a 2x16 matrix with the first two rows (1:2,:) being matrix 1 and the next set (3:4,:) being matrix 2 and so on. I have tried reshape but have failed to get this working. I want something like this, where 1) is the matrix number:
Any advice would be appreciated. I am trying to avoid for loops for speed as my matricies become extremely large.

After the 2 lines of code above, use
res = reshape(TEMP, [16 2])
See the documentation here:
(The code shown above produces the exact same output you mentioned in your question.)
