Similarity Matrix


Similarity Matrix is a two-dimensional graphical display of all pair-wise distances between a set of features or samples. Distances can be calculated in a number of ways, including Euclidean distance, the square of the Euclidean distance, correlation, the absolute value of the correlation, and city block.
