5 string references to 'RealVector'

Matrix::row_vectors in ./Matrix.php

Only return the row vectors that have at least one element. Work for both RealMatrix and SparseMatrix

RecommenderMatrixTestCase::testVector in ./recommender.test

SparseVector::common_items in ./Matrix.php

Vector::create in ./Matrix.php

Factory method to create a vector. Note, no parameter checking. Array index has to be [0..n), otherwise program unstable

Vector::wrap in ./Matrix.php

Factory method. Wrap the array of numbers into the vector. Note: passing by reference!

Vector::$count	protected	property
Vector::$mean	protected	property
Vector::$std	protected	property
Vector::$values	protected	property
Vector::$variance	protected	property
Vector::correlation		function	Compute correlation with $vector. No caching option. Works for RealVector. SparseVector needs additional handling.	1
Vector::count		function	Count the number of vectors. This works for SparseVector too. It only counts valid numbers, not the size the vector is supposed to be.
Vector::covariance		function	Compute covariance with $vector. No caching option. Works for RealVector. SparseVector needs additional handling.	1
Vector::create	static	function	Factory method to create a vector. Note, no parameter checking. Array index has to be [0..n), otherwise program unstable
Vector::get		function
Vector::mean		function	Calculate the mean. This works for SparseMatrix too.
Vector::set		function
Vector::std		function
Vector::variance		function	Calculate the variance. This works for SparseMatrix too.
Vector::wrap	static	function	Factory method. Wrap the array of numbers into the vector. Note: passing by reference!
Vector::__construct	protected	function
