[Python知识库]python保存读取mat文件

1.使用python将数组存为mat文件

import numpy as np
import scipy.io as scio

data = np.random.randn(4,3)
print('data.shape:', data.shape)
print('data \n', data)

#//保存mat文件
scio.savemat('test.mat', {'array': data})

输出结果：

data.shape: (4, 3)
data 
 [[-0.40026532 -0.89590894 -0.786739  ]
 [-0.88980627  0.81444202  0.34033266]
 [-0.30045292  0.98880767 -0.03519286]
 [ 2.07324159 -0.70659934 -0.01854175]]

2.使用python读取mat文件

read = scio.loadmat('test.mat')['array']
print('read.shape:', read.shape)
print('read:\n', read)

输出结果：

read.shape: (4, 3)
read:
 [[-0.40026532 -0.89590894 -0.786739  ]
 [-0.88980627  0.81444202  0.34033266]
 [-0.30045292  0.98880767 -0.03519286]
 [ 2.07324159 -0.70659934 -0.01854175]]
