我找到了两种方法:scipy 或 mat4py。
- mat4py
从 MAT 文件加载数据
函数 loadmat 将 MAT 文件中存储的所有变量加载到
简单的Python数据结构,仅使用Python的dict和list
对象。数字和元胞数组转换为行序嵌套
列表。数组被压缩以消除只有一个元素的数组。
生成的数据结构由简单类型组成,这些类型是
兼容JSON格式。
示例:将 MAT 文件加载到 Python 数据结构中:
data = loadmat('datafile.mat')

- Scipy:
Example:
import numpy as np
from scipy.io import loadmat # this is the SciPy module that loads mat-files
import matplotlib.pyplot as plt
from datetime import datetime, date, time
import pandas as pd
mat = loadmat('measured_data.mat') # load mat-file
mdata = mat['measuredData'] # variable in mat file
mdtype = mdata.dtype # dtypes of structures are "unsized objects"
# * SciPy reads in structures as structured NumPy arrays of dtype object
# * The size of the array is the size of the structure array, not the number
# elements in any particular field. The shape defaults to 2-dimensional.
# * For convenience make a dictionary of the data using the names from dtypes
# * Since the structure has only one element, but is 2-D, index it at [0, 0]
ndata = {n: mdata[n][0, 0] for n in mdtype.names}
# Reconstruct the columns of the data table from just the time series
# Use the number of intervals to test if a field is a column or metadata
columns = [n for n, v in ndata.iteritems() if v.size == ndata['numIntervals']]
# now make a data frame, setting the time stamps as the index
df = pd.DataFrame(np.concatenate([ndata[c] for c in columns], axis=1),
index=[datetime(*ts) for ts in ndata['timestamps']],
columns=columns)

- 最后你可以使用 PyHogs 但仍然使用 scipy:
阅读综合体.mat
files.
本笔记本展示了读取 Matlab .mat 文件的示例,
使用循环将数据转换为可用的字典,一个简单的图
的数据。
