numpy.linalg.inv(a) 1. 这里的参数a是需要计算逆的方阵。 使用示例 importnumpyasnp# 创建一个示例方阵A=np.array([[4,7],[2,6]])# 计算逆矩阵A_inv=np.linalg.inv(A)print("原矩阵 A:")print(A)print("逆矩阵 A_inv:")print(A_inv)# 验证 A * A_inv 是否等于单位矩阵identity_matrix=np...

NumPy 逆矩阵 Python 原创 mob64ca12f21246 2月前 72阅读 hibernateinverse作用 Inverse是hibernate双向关系中的基本概念。inverse的真正作用就是指 定由哪一方来维护之间的关联关系。当一方中指定了“inverse=false”(默认),那么那一方就有责任负责之间的关联关系,说白了就是 hibernate如何生成Sql来维护关联的记录!
