Description

The matrix representation for the example decision tree on the Decision Tree Documentation has a minor error on Row 3, Col 2. The value here should be moved to Row 3, Col 3 as it refers to the feature index for node 3. Node 2 isn't an internal node and therefore, the value at Row 3, Col 2 should be 0.

Current:

	Col 1	Col 2	Col 3	Col 4	Col 5
Row 1	1	2	3	6	7
Row 2	1	0	1	0	0
Row 3	3	5	0	0	0
Row 4	1	1	2	2	1
Row 5	1	0	2	0	0
Row 6	0.45	0	2	0	0
Row 7			3

Suggested:

	Col 1	Col 2	Col 3	Col 4	Col 5
Row 1	1	2	3	6	7
Row 2	1	0	1	0	0
Row 3	3	0	5	0	0
Row 4	1	1	2	2	1
Row 5	1	0	2	0	0
Row 6	0.45	0	2	0	0
Row 7			3
