LATIN_EDGE_DATASET
Generate Latin Edge Square Datasets


LATIN_EDGE_DATASET is a MATLAB program which creates a Latin Edge Square dataset.

A Latin square, in M dimensional space, with N points, can be thought of as being constructed by dividing each of the M coordinate dimensions into N equal intervals. The I-th coordinates of the N subsquares are defined by assigning each possible value exactly once to one subsquare. Such a set is called a Latin Square.

Now suppose that, in each spatial coordinate, we label successive squares by the values 0, 1/N-1, 2/N-1, ..., (N-2)/(N-1), 1. Then each element of our Latin Edge dataset is a vector of N such values, and our dataset contains N such vectors.

Usage:

r = latin_edge_dataset ( m, n, seed )
where The data is written to the file latin_edge_m_n.txt.
