NameError: name 'mat_dict' is not defined

In the develop branch, I try to run the mnist example in the file examples/mnist/minst.py

Here is the bug of running the code:

Traceback (most recent call last):
  File "C:\Users\yezhu\OneDrive\Desktop\torchquantum\examples\mnist\mnist.py", line 281, in <module>

NameError: name 'mat_dict' is not defined

There is an unresolved reference of 'mat_dict' in the file "\torchquantum\functional\sx.py".

Thanks for catching this issue! This is actually resolved in #206 (specifically ffaaefa), so it shouldn’t be a problem once the PR is merged in!

Marking as closed, resolved in the most recent release!
