MATLAB: Index loop into matrix

for looploopmatrix array

Hi
Im very new to MatLab.
Im trying to get this loop to produce a 10×3 matrix and not 10 sepperate answers. 
triCoord=10x9
ntri = 10
qTop = zeros(ntri,3)
for n=1:ntri
qTop =[]
qTop(n,:) = [qTop
         mean(triCoord(n,[1 4 7])),mean(triCoord(n,[2 5 8])),mean(triCoord(n,[3 6 9]))]
end
qTop

Best Answer

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
