I have a 802x1. I would like to move/insert row 801 right after 400. so that 801 is the new 401.

If m is a matrix m = [m(1:400,:);m(801,:);m(401:800);m(802:end,:)];
If m is a row vector remove the ,: in each above.
If m is a column vector or otherwise I don't understand the question.

@Miri you could do this implace if you are concerned with the memory associated with creating another array/matrix:
m801 = m(801,:);
m(402:801,:) = m(401:800,:);
m(401,:) = m801;

result = M([1:400,801,401:800,802])
