Dissimilarities Constructor (Double[,], Int32, Int32, Int32)

Constructor for Dissimilarities.

public Dissimilarities(
   double[,] x,
   int distanceMethod,
   int distanceScale,
   int iRow
);

Parameters

x: A double matrix containing the data input matrix.
distanceMethod: An int identifying the method to use in computing the dissimilarities or similarities.
distanceScale: An int containing the scaling option.
iRow: An int identifying whether distances are computed between rows or columns of x.

Remarks

Acceptable values of distanceMethod are 1, 2, ..., 8. See Remarks section of the Dissimilarities documentation for a description of these methods.

distanceScale	Method
0	No scaling is performed.
1	Scale each column (row if iRow=1) by the standard deviation of the column(row).
2	Scale each column (row if iRow=1) by the range of the column (row).

If iRow = 1, distances are computed between the rows of x. Otherwise, distances between the columns of x are computed.

Exceptions

Exception Type	Condition
ScaleFactorZeroException	is thrown when computations cannot continue because a scale factor is zero.
NoPositiveVarianceException	is thrown when no variable has positive variance
ZeroNormException	is thrown when the Euclidean norm of a column is equal to zero
