Parameters

matrix
Type: SystemDouble
A number multi-dimensional array containing the matrix values.
means
Type: SystemDouble
The mean value of the given values, if already known.
divisor
Type: SystemDouble
A real number to divide each member of the matrix.
dimension
Type: SystemInt32
Pass 0 to if mean vector is a row vector, 1 otherwise. Default value is 0.

Return Value

Type: Double
The covariance matrix.
Remarks
By dividing the Scatter matrix by the sample size, we get the population Covariance matrix. By dividing by the sample size minus one, we get the sample Covariance matrix.
