MATLAB: CAT arguments dimensions are not consistent.

color

for i = 1:size(LinkMat,1)

    d = LinkMat(:,6)/(c*10);
    plot([LinkMat(i,2),LinkMat(i,4)],[LinkMat(i,3),LinkMat(i,5)], 'Color', [0 d 0] );
end

I am getting error at the Plot function probably due to Color. Can't we specify a variable in the matrix ???

as you get CAT dimensions consistency then your equation " d = LinkMat(:,6)/(c*10);" does not return a scalar but a matrix , try to correct so as the color vector to be comprised of three scalars

MATLAB: Comparing arrays using loop

You can actually do this in Matlab without needing a for loop. If I'm interpreting your question correctly, you're asking to find which row in a matrix contains the maximum sum. To achieve this, use the max and sum commands.

    totWatch = sum(Matrix2,2); %Sum along dimension #2 (columns)
    totBought = sum(Matrix3,2);

This gives us two vectors of 3x1 (cat, dog, hamster). Let's find which have a watch count above 50 AND a sell count above 30:

    isPopular = (totWatch > 50) & (totBought > 30)

isPopular =

     0
     0
     1

So strangely, hamsters are more popular than dogs. To find the most popular of each in an automated fashion you can use the max command, which can give you both the max value and the index of that value. For the most bought, for instance:

    [maxB, ixB] = max(totBought)

maxB =

ixB =

Tells us that 42 pets of one type were sold, and this occurred in Row 3, the hamsters.

MATLAB: CAT arguments dimensions are not consistent. How to solve this problem

You might have a cell in the cell array A whose content doesn't have the same number of elements as the others, which prevents the CAT operation in CELL2MAT. You can check it out with:

 >> cellfun(@numel, A)

If you don't get an array filled with one, unique value, you cannot use CELL2MAT.
