Method std

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

Calculates the standard deviation of the tensor.

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

The tensor containing the source values.
int64 option ddof

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

The standard deviation estimate.
Remarks

The standard deviation is calculated over all elements of the tensor.

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.std a
