| FloatMatrixApplyColumns Method |
Returns a new vector containing an element for each column in this matrix.
The elements are the results of applying a function that takes a vector and
returns a single-precision number.
Namespace: CenterSpace.NMath.CoreAssembly: NMath (in NMath.dll) Version: 7.4
Syntax public FloatVector ApplyColumns(
Func<FloatVector, float> function
)
Public Function ApplyColumns (
function As Func(Of FloatVector, Single)
) As FloatVector
public:
FloatVector^ ApplyColumns(
Func<FloatVector^, float>^ function
)
member ApplyColumns :
function : Func<FloatVector, float32> -> FloatVector
Parameters
- function FuncFloatVector, Single
-
A delegate object representing a function that
takes a FloatVector parameter and returns a float.
Return Value
FloatVectorA vector
v with the same length as the number of columns in this
matrix, where
v[i]=function( this.Col(i) ).
Remarks
To apply a function to the rows of a matrix, first Transpose() the matrix, then
call ApplyColumns(). Transpose() again to return the matrix to its
original view. Transposing just swaps the number of rows and the number of columns,
as well as row strides and column strides. No data is copied.
