ProductOfDifferences(ReadOnlySpan<Single>, ReadOnlySpan<Single>)	计算指定非空张量中单精度浮点数的元素差异乘积。
ProductOfDifferences<T>(ReadOnlySpan<T>, ReadOnlySpan<T>)	计算指定非空张量中数字的元素差异乘积。

ProductOfDifferences(ReadOnlySpan<Single>, ReadOnlySpan<Single>)

Source:: TensorPrimitives.cs

Source:: TensorPrimitives.Single.cs

计算指定非空张量中单精度浮点数的元素差异乘积。

public:
 static float ProductOfDifferences(ReadOnlySpan<float> x, ReadOnlySpan<float> y);

public static float ProductOfDifferences (ReadOnlySpan<float> x, ReadOnlySpan<float> y);

static member ProductOfDifferences : ReadOnlySpan<single> * ReadOnlySpan<single> -> single

Public Shared Function ProductOfDifferences (x As ReadOnlySpan(Of Single), y As ReadOnlySpan(Of Single)) As Single

参数

x: ReadOnlySpan<Single>

第一个张量，表示为范围。

y: ReadOnlySpan<Single>

第二个张量，表示为范围。

Single

将第二张张量中的元素与第一张张量相乘的结果。

例外

ArgumentException

x 和 y 的长度必须相同。

注解

此方法有效计算： Span<float> differences = ...; TensorPrimitives.Subtract(x, y, differences); float result = TensorPrimitives.Product(differences); ，但不需要额外的临时存储来提供中间差异。

此方法可以调用基础 C 运行时，或使用特定于当前体系结构的说明。不同的操作系统或体系结构之间的确切结果可能有所不同。
