SampleCovariance( X : Array[I,R] ; I,J,R : IndexType )
Returns a correlation matrix based on data in X, where each data point is a vector indexed by I, and the entries in the correlation matrix are the pair-wise correlations of the columns of data. A second index, J, of size identical to I, is required in order to index the 2-dimensional result.
