When you are working in MATLAB, get used to the idea that you can reshape a matrix to perform some operation.

MATLAB: Index loop into matrix

triCoord= zeros(10,9);
ntri = 10
qTop = zeros(ntri,3);
for n=1:ntri
qTop(n,:) = [mean(triCoord(n,[1 4 7])),mean(triCoord(n,[2 5 8])),mean(triCoord(n,[3 6 9]))];
end
qTop
