hi all,
can you advise me how to write my for loop output as matrix as below:
board 1 = 3x4matrix
board 2 = 3x4martix
for boardIdx = 1:params.NumPatterns %board number
R = params.RotationMatrices(:, :, boardIdx)';
t = params.TranslationVectors(boardIdx, :)';
worldBoardCoords = bsxfun(@plus, R * wpConvHull, t); %3x5 matrix
worldBoardCoords = worldBoardCoords(:,1:4) %3x4 matrix
end

output=zeros(3,4)
for i=1:3
for j=1:4
output(i,j)=........% Evaluate output
end
end
In most cases, you can avoid the loop (If not necessity), note on it.

hi Kalyan, thanks for your reply. is it possible to use bsxfun(@plus, a, t) where:
a = 3x5x9 and t = 3x9? i need to add a(:,:,1) + t(:,1), a(:,:,2) + t(:,2) and so on.
i tried it but it give me error "Error using bsxfun Non-singleton dimensions of the two input arrays must match each other."
sorry this is out of the scope of main question
