print(random_matrix) 或者,如果你在一个函数中生成随机矩阵,可以将其返回: python def generate_random_matrix(rows, cols): return np.random.rand(rows, cols) random_matrix = generate_random_matrix(4, 5) print(random_matrix) 综上所述,使用numpy生成随机矩阵的完整代码示例如下: python import numpy...
np.eye函数用于生成一个对角线元素为 1,其余元素为 0 的单位矩阵: matrix_eye=np.eye(4)print("4x4 identity matrix:")print(matrix_eye) 1. 2. 3. 3.4 使用np.random.rand np.random.rand函数可以生成一个指定形状的矩阵,其元素是 [0, 1) 区间内的随机数: matrix_random=np.random.rand(4,4)print...
