Python numpy.array2string函数方法的使用 numpy.array2string 函数用于将 NumPy 数组转换为字符串表示。它允许你自定义输出格式,包括精度、分隔符、行和列的宽度等。本文主要介绍一下NumPy中array2string方法的使用。 numpy.array2string numpy.array2string(a, max_line_width=None, precision=None, suppress_small...
np.array(['one', 'dim', 'list'], ndim=2).T-> column vector(single-column matrix, nx1) np.asmatrix(list)返回矩阵,如果list是一维的,则返回nx1矩阵(行向量),转置后成为1xn矩阵(列向量)。 np.unique(arr, return_index, return_counts)查找数组中具有唯一性的元素。
