Returns a new numeric column with the given name and same size as this column, whose values are the result of applying the given double binary function to each element of this column. The first parameter to the binary function is an element of self; the second parameter is the corresponding element of the passed vector.

Syntax

C#
public DFNumericColumn Apply(
	string name,
	NMathFunctions..::.DoubleBinaryFunction function,
	DoubleVector v
)
Visual Basic (Declaration)
Public Function Apply ( _
	name As String, _
	function As NMathFunctions..::.DoubleBinaryFunction, _
	v As DoubleVector _
) As DFNumericColumn
Visual C++
public:
DFNumericColumn^ Apply(
	String^ name, 
	NMathFunctions..::.DoubleBinaryFunction^ function, 
	DoubleVector^ v
)

Parameters

name
Type: System..::.String
Name for the new column.
function
Type: CenterSpace.NMath.Core..::.NMathFunctions..::.DoubleBinaryFunction
A delegate object representing a function that takes two double parameters and returns a double.
v
Type: CenterSpace.NMath.Core..::.DoubleVector
A vector of parameters to function.

Return Value

A column with the same name and size as self and with c[i] = function( this[i], v[i] )

Remarks

An attempt will be made to convert each value in this column to a double to perform the operation. No data in this column will be changed.

Exceptions

ExceptionCondition
CenterSpace.NMath.Core..::.MismatchedSizeExceptionThrown if the passed vector is not the same length as this column.
CenterSpace.NMath.Core..::.InvalidArgumentException Thrown if the values in this column cannot be converted to numeric values.
