array([[1, 2, 3], [4, 5, 6]]) dimensions = matrix.shape print("矩阵的维度:", dimensions) Python Copy输出结果为:矩阵的维度: (2, 3) Python Copy使用Python内置函数除了使用NumPy库,我们还可以使用Python的内置函数来查找矩阵的维度。通过使用len函数和[0]索引,我们可以找到矩阵的行数。同样地,...
indices:An integer array whose elements are indices into the flattened version of an array of dimensions ``shape``. 表示一个索引,这个索引是将维度为shape参数的矩阵展平后的索引。shape:The shape of the array to use for unraveling ``indices``. 用来解开 indices 的 数组形状。 order :{'C', '...

NumPy arrays are n-dimensional array objects and they are a core component of scientific and numerical computation in Python. NumPy数组是n维数组对象,是Python中科学和数值计算的核心组件。 NumPy also provides tools for integrating your code with existing C,C++, and Fortran code. NUMPY还提供了将代码...
In Python, the broadcasting of arrays generally allows NumPy to perform element-wise operations between two arrays of different dimensions in which the smaller array is extended virtually in order to match the size of the larger array. Broadcasting Rules: If arrays have different numbers of dimensio...
xarray(pronounced "ex-array", formerly known asxray) is an open source project and Python package that makes working with labelled multi-dimensional arrays simple, efficient, and fun! Xarray introduces labels in the form of dimensions, coordinates and attributes on top of rawNumPy-like arrays, ...
