我正在尝试将某些.mat文件加载到python中。在为我创建它们时,我无法用其他方式保存它们。
我正在尝试以下操作:
import numpy as np
import matplotlib.pyplot as plt
import scipy.io as sio
dat = sio.loadmat(Filename)
当我打印dat
时,我得到:

dtype=[('L', 'O'), ('Lreg', 'O'), ('R', 'O'), ('Rreg', 'O'), ('sol', 'O')])}
但是我需要的是L
,R
,Lreg
,Rreg
和sol
作为numpy数组。
如何将数组与变量关联并提取所需的数据?
答案 0 :(得分:0)
dat
是字典。 dat['dat']
是一个数组。
L = dat['dat']['L']
是该数组的字段。
然后检查L
和dtype
的形状。您可能需要另一层索引才能获取数字数组,例如
L[0,0]
L.item()
