1 year ago Try to restart Matlab to make the new static Java path takes effect.
After installing traci4matlab, running traci_test.m has the following error: 错误使用 traci.Socket/connect (line 25) Java exception occurred: java.net.ConnectException: Connection refused: connect

D:\Program Files\matlab\R2017b\toolbox\traci4matlab\traci4matlab\examples>
During the installation process in Step 3"Adding the additional dependencies to the Matlab’s static Java path", my javaclasspath.txt is "D:\Program Files\matlab\R2017b\toolbox\traci4matlab\traci4matlab\traci4matlab.jar" and the "D:\Program Files\matlab\R2017b\toolbox\traci4matlab\traci4matlab" is the path to the root folder of TraCI4Matlab. How can i do for it?
