Measure the total height of a stat-tree
[maxheight, cost] = CalcTreeHeight(stree,D)
stat tree (e.g. generated by CalcStatTree)
maximum depth of search
Height of the tree, assigning to each branch a length, equal to the entropy drop between parent and child
Tree of entropy drops associated with various splits
This is a utility used by PlotBasisTree to set scale for plotting It is not intended for other use.
