In mathematics, cross-product is simply a binary operation that is performed on two vectors in 3-dimensional space. The final generated output vector will always be perpendicular to the input vector. Vector products are also referred to as cross products. They are denoted by “A” x ”B”. ...
接下来,我们使用numpy.cross函数来计算这两个向量的叉乘: python # 计算叉乘 cross_product = np.cross(vector1, vector2) print("叉乘结果:", cross_product) 5. 验证叉乘结果的正确性 为了验证叉乘结果的正确性,我们可以手动计算或使用其他工具进行验证。对于上述示例,叉乘结果应为[-3, 6, -3],因为:∣...
numpy.cross 函数计算两个三维向量的叉乘结果,返回垂直于输入向量的向量。 使用场景 常用于计算向量的法向量、力矩等,例如在物理学、计算机图形学中应用广泛。 用法及示例 import numpy as np vector1 = [1, 0, 0] vector2 = [0, 1, 0] cross_product = np.cross(vector1, vector2) print(cross_product...
np.cross(x, y) computes the cross product of two arrays in a 3-dimensional space. The cross product of two 1-D arrays returns a vector perpendicular to both input vectors. In the given code, x and y are 1-D arrays, and the output is the cross product of x and y, which is a ...
