Computes the element-wise natural (base e) logarithm of numbers in the specified tensor plus 1.

public:
generic <typename T>
 where T : System::Numerics::ILogarithmicFunctions<T> static void LogP1(ReadOnlySpan<T> x, Span<T> destination);

public static void LogP1<T> (ReadOnlySpan<T> x, Span<T> destination) where T : System.Numerics.ILogarithmicFunctions<T>;

static member LogP1 : ReadOnlySpan<'T (requires 'T :> System.Numerics.ILogarithmicFunctions<'T>)> * Span<'T (requires 'T :> System.Numerics.ILogarithmicFunctions<'T>)> -> unit (requires 'T :> System.Numerics.ILogarithmicFunctions<'T>)

Public Shared Sub LogP1(Of T As ILogarithmicFunctions(Of T)) (x As ReadOnlySpan(Of T), destination As Span(Of T))

Type Parameters

T

Parameters

x: ReadOnlySpan<T>

The tensor, represented as a span.

destination: Span<T>

The destination tensor, represented as a span.

Exceptions

ArgumentException

x and destination reference overlapping memory locations and do not begin at the same location.

Remarks

This method effectively computes destination[i] = T.LogP1(x[i]).

If a value equals 0, the result stored into the corresponding destination location is set to NegativeInfinity. If a value is negative or equal to NaN, the result stored into the corresponding destination location is set to NaN. If a value is positive infinity, the result stored into the corresponding destination location is set to PositiveInfinity. Otherwise, if a value is positive, its natural logarithm plus 1 is stored into the corresponding destination location.

This method may call into the underlying C runtime or employ instructions specific to the current architecture. Exact results may differ between different operating systems or architectures.
