范例

打开所有单元 关闭所有单元

基本范例  (2)

嵌入维度：

Wolfram Language code: RegionEmbeddingDimension[EmptyRegion[7]]

域隶属条件：

Wolfram Language code: RegionMember[EmptyRegion[3], {x, y, z}]

范围  (8)

Regions  (8)

嵌入维度：

Wolfram Language code: RegionEmbeddingDimension[EmptyRegion[3]]

几何维度：

Wolfram Language code: RegionDimension[EmptyRegion[3]]

点隶属测试：

Wolfram Language code: RegionMember[EmptyRegion[4], {1, 2, 3, 4}]

获取点隶属的条件：

Wolfram Language code: RegionMember[EmptyRegion[4], {x, y, z, t}]

从一个点的距离：

Wolfram Language code: RegionDistance[EmptyRegion[2], {1, 1}]

从一个点的有符号的距离：

Wolfram Language code: SignedRegionDistance[EmptyRegion[2], {1, 1}]

域中的最近点：

Wolfram Language code: RegionNearest[EmptyRegion[2], {1, 1}]

一个有界空域：

Wolfram Language code: BoundedRegionQ[EmptyRegion[3]]
Wolfram Language code: RegionBounds[EmptyRegion[3]]

在空域上求积分：

Wolfram Language code: Integrate[x ^ 2 + y ^ 2 + z ^ 2, {x, y, z}∈EmptyRegion[3]]

对其取最优化：

Wolfram Language code: ℛ = EmptyRegion[2];
Wolfram Language code: MinValue[{(x - 3)^2(y - 1)^2 + 1, {x, y}∈ℛ}, {x, y}]

在空域上求解：

Wolfram Language code: ℛ = EmptyRegion[2];
Wolfram Language code: Reduce[x^2 + y^2 == 1 && {x, y}∈ℛ, {x, y}]
