mapmind

This function implements a non-linear alignment algorithm for two parameter sets (each defined by a vector or matrix). The method minimizes the accumulated Euclidean distance of the two sets. The result is a two column matrix containing the index map of the alignment. The function also implements a method to create a mapped-copy of the sets.

Usage 1

mapmind(0, a, b)

a, b

Are vectors are matrices containing the two parameter sets;

nrow(a)>2, nrow(b)>2, ncol(a) = ncol(b)

Each row of a/b defines one parameter value or vector (e.g. for a frame).

Result:

An index map for vectors a and b with the minimum distance matrix with 2 columns, 1st column is index(a), 2nd column = index(b).

The number of rows is the length of the aligned path

Usage:

map := mapmind(1, map, x)

Parameters:

map

A vector containing the index map.

x

A vector or matrix to copy or remap.

Result:

mappedX[ rows(map), columns(x) ]
