我想在PyCharm IDE中看到Plotly的HTML输出.它目前说:
进程以退出代码0结束
输出.但是,我在Jupyter中收到了一个图形结果
我有一个数字矩阵:
[[a, b, c]
[d, e, f]
[g, h, i]]

我想据此进行镜像:

然后再次产生:
[[i, h, g, h, i]
[f, e, d, e, f]
[c, b, a, b, c]
[f, e, d, e, f]
[i, h, g, h, i]]

我想坚持使用像numpy这样的基本Python包。在此先感谢您的帮助!

我对功能/公式本身没有疑问,
提供:
def get_bearing(lat1, long1, lat2, long2):
dLon = (long2 - long1)
y = math.sin(dLon) * math.cos(lat2)
x = math.cos(lat1) * math.sin(lat2) - math.sin(lat1) * math.cos(lat2) * math.cos(dLon)
brng = math.atan2(y, x)
brng = np.rad2deg(brng)
return brng

问题是结果不是预期的。
该函数的预期用途返回(很长)列表中两个经纬度对之间的方位,即
lat1 = path[int(len(path) * location / 1000)][0]
lat2 = path[int(len(path) * location / 1000) + 1][0]
lng1 = path[int(len(path) * location / 1000)][1]
lng2 = path[int(len(path) * location / 1000) + 1][1]

然后,方位结果会更改图的视图方向,其中方位可以采用[-180,180]范围内的值。理想情况下,结果应显示为使得lat1,lng1和lat2,lng2之间形成的线在图中完全是“垂直”的(在图中切换了经纬度注释),请参见下文
我希望有人可以从函数返回的方位以及预期方位应该是什么来推断问题。以下是一些实例:
