Properties 1and2are useful for verifying that a matrix is a rotation matrix. If you manipulate a matrix, and you want to make sure that you still have a rotation matrix, sum the squares of any row or column. If the result is not 1, then you have surely done something wrong. If the...
The correlation matrix illustrates a strong correlation (0.93) between NoP and h_d (tree slenderness), as well as NoP and the diameters RCD, and DBH. All climatic parameters show a weak correlation to all tree, stand, and climatic variables. Noticeable is the temperature, with a correlation ...
