Functions ¶
func Describe ¶
Describe calculates the persistence landscape functions λₖ for the interval data in the provided Interface. fn is called for each position t of the span of the interval data with the values for t and the k λ functions at t. Explicit zero values for a λₖ(t) are included only at the end points of intervals in the span.
func DescribeTree ¶
DescribeTree calculates the persistence landscape functions λₖ for the interval data in the provided interval tree. fn is called for each position t of the span of the interval data with the values for t and the k λ functions at t. Explicit zero values for a λₖ(t) are included only at the end points of intervals in the span. Note that intervals stored in the tree must have unique id values within the tree.
