Assembly: Novacta.Analytics (in Novacta.Analytics.dll) Version: 2.1.0+428f3840cfab98dda567bb0ed350b302533e273a

C#

public static explicit operator CategoricalVariable (
	DoubleMatrix value
)

VB

Public Shared Narrowing Operator CType ( 
	value As DoubleMatrix
) As CategoricalVariable

C++

static explicit operator CategoricalVariable^ (
	DoubleMatrix^ value
)

F#

F# does not support the declaration of new casting operators.

Parameters

value DoubleMatrix: The object to convert.

Return Value

CategoricalVariable
The converted object.

Remarks

The matrix is successfully converted only if it represents a column vector. The variable result of the conversion will have a number of categories equals the matrix number of rows. Each matrix row corresponds to a category, whose code is the value on the row, while its label is the row name, if any, or the result of the conversion of the code to a string. The name of the matrix is set equal to the variable name.

Exceptions

ArgumentNullException	value is null.
ArgumentOutOfRangeException	value is not a column vector.
InvalidOperationException	value has two equal entries. -or- value has two rows having the same name.
