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.
