public class MatrixReader
extends java.lang.Object

Reads a Matrix from the specified reader. The format is an (MxN) array of doubles, WITHOUT specifying the dimensions explicitly. We determine the matrix dimensions by first reading all the rows (Vectors) of the file, then ensuring that each row (Vector) has the same dimension.
