I have a vector K = [1.7135 3.2725 4.0000 3.2725 1.7135 0.4775 0.0365 0 0.0365 0.4775]. How do I take the mean of all of the sets of two sequential elements of this vector without using a "for" loop? Example: Mean of K(1) and K(2), K(2) and K(3), K(3) and K(4) etc. And then put all of those individual means into a single vector?
Thanks.

Sounds like homework.
Hint: A(1:end-1) and A(2:end)

Use a convolution.
conv(data,[0.5 0.5])
should be a good start.
