MatlabOpenIGTLink can only act as a client. A client can send and receive data as well.

If you want Matlab to act as server then you can use the pyigtl Python package.

Hello Professor  lassoan ， Here is one more problem when slicer as server and matlab as client，I run testSendMessage.m，and the connect is successful when i send a transform to slicer ，the slicer can received it as target_001. and i try to change the transform value,but the transform in slicer didn't change . Here is the transform i send to slicer Can you tell me why the lineartransform didn't change its pose in  3D slicer when i change the transform value in matlab. By the way，the below web link is my another problem ： https://discourse.slicer.org/t/i-got-a-error-in-the-tutorial-of-building-software-systems-for-image-guided-robot-assisted-interventions/25071/2 And i have post it on slicer discourse，but yet i still can‘t solve it，could you help me this problem  Thanks for you help.
