python中如何将​matlab.dou​ble转化为tens​or

eng = matlab.engine.start_matlab() # 可以调用matlab的内置函数。

output = eng.test(indata)

上述代码中output类型为matlab.double，如果想要将其转化为pytorch中的tensor类型，该怎么做？

Hi quio cheng!

To convert a 'matlab.double' variable to a 'Tensor' in Python, you can use the 'numpy' library to first convert the matlab.double to a NumPy array, and then convert the 'NumPy array' to a 'Tensor'.

Start by loading your matlab.double array:

myData = eng.eval("load('{}','cluster_class','par')".format('sampleData.mat')) 

With MATLAB R2022a and later, you can convert matlab.double directly to a numpy array:

a = np.array(myData['cluster_class']) 

if you are using pytorch then

import torch 
x_tensor = torch.tensor(a) 

if you are using tensorflow then

import tensorflow as tf 
data_tf = tf.convert_to_tensor(a) 

Hope this helps!

Thank you.
