Method varAxis

static member varAxis: int * Tensor<'T> * int64 option -> Tensor<'T>

Calculates the variance of the elements along the specified axis.

Declaration
static member varAxis: axis:int * a:Tensor<'T> * ddof:int64 option -> Tensor<'T>
Parameters
Type Name Description
int axis
Tensor<'T> a

The tensor containing the source values.
int64 option ddof

The delta degrees of freedom. (default: 0L)
Returns
Type Description
Tensor<'T>

A new tensor containing the result of this operation.
Remarks

The variance is calculated along the specified axis.

The parameter ddof specifies the difference between the number of elements and the degrees of freedom for the computation of the variance. Use ddof=1 to obtain an unbiased estimate and ddof=0 for a maximum-likelihood estimate.

Examples
 let a = HostTensor.ofList2D [[1.0; 2.0; 3.0; 4.0]
                              [5.0; 6.0; 7.0; 8.0]]
 let b = Tensor.varAxis (1, a, ddof=1L)
