Python numpy.asmatrix() numpy.asmatrix(data, dtype =None)通过将输入解释为一个矩阵返回一个矩阵。 参数 : data :类似数组的输入数据 dtype : 返回数组的数据类型 返回值 : Interprets the input as a matrixPythonCopy # Python Programming illustrating # numpy.asmatrix import numpy as geek # array-like input b = geek.matrix([[5, 6, 7], [4, 6]]) print("Via array-like input : \n", b, "\n") c = geek.asmatrix(b) b[0, 1] = 10 print("c matrix : \n", c) PythonCopy 输出 : Via array-like input : [[[5, 6, 7] [4, 6]]] c matrix : [[[5, 6, 7] 10]] PythonCopy
