Class Documentation¶

class PackedIndex¶

An iterator-like object to help in traversing “packed” shapelet or Hermite polynomial matrix or vector dimensions.

A pair of indices (x,y) is mapped to the packed position i = (x+y)(x+y+1)/2 + x.

Typical usage is in a nested loop of the form:

for (PackedIndex i; i.getOrder() <= order; ++i) {
    // utilize i
}
