Bug in TriangleMesh

[weihuayi]

我有一段如下的代码，展示 MeshFactory 的用法

import numpy as np 
import matplotlib.pyplot as plt 

from fealpy.mesh import MeshFactory as MF 

box = [0, 1, 0, 1] 
  
mesh = MF.boxmesh2d(box, nx=10, ny=10, meshtype='tri') 
mesh = MF.boxmesh2d(box, nx=10, ny=10, meshtype='quad') 
mesh = MF.boxmesh2d(box, nx=10, ny=10, meshtype='poly') 
  
fig = plt.figure() 
axes= fig.gca() 
mesh.add_plot(axes) 
plt.show()

但运行遇到了问题， 报错信息如下：

Traceback (most recent call last):
  File "mf.py", line 24, in <module>
    mesh = MF.boxmesh2d(box, nx=10, ny=10, meshtype='poly')
  File "/home/why/git/fealpy/fealpy/decorator/timer.py", line 20, in run
    val = func(*args, **kwargs)
  File "/home/why/git/fealpy/fealpy/mesh/MeshFactory.py", line 171, in boxmesh2d
    pnode, pcell, pcellLocation = mesh.to_polygonmesh()
  File "/home/why/git/fealpy/fealpy/mesh/TriangleMesh.py", line 1057, in to_polygonmesh
    node2cell = self.ds.node_to_cell(localidx=True)
TypeError: node_to_cell() got an unexpected keyword argument 'localidx'

我认为这里是代码的一个 bug。

? 我这里可以正常运行 😂

这个是一个issue 示例😂，我给学生上课想让他们也养成在这里提问的习惯

给魏老师说个好用的小技巧，github上可以直接引用code：在网页界面下浏览code，左边的行数选中之后右键点permanent link，copy pasta到这里就会自动生成preview而且指回原code
