time_from_start of JointTrajectory on RosMatlab

edit

Nice to meet you. I am Jun from Germany. I am using the RosMatlab I/O package released on january 2014. I am having problems when trying to publish a JointTrajectory from Matlab.

Because I can’t find the way how to set “time_from_start”, it happens a publish error on Matlab now. Could you teach me how to set the“time_from_start” on RosMatlab?

with the next code :

node = rosmatlab.node('PublishTrajectory', [], [], 'rosIP', '127.0.0.1'); publisher = rosmatlab.publisher('Traj', 'trajectory_msgs/JointTrajectory', node);

msg = rosmatlab.message('trajectory_msgs/JointTrajectory', node); po = rosmatlab.message('trajectory_msgs/JointTrajectoryPoint', node);

p1 = msg.getPoints(); po.setTimeFromStart(1); p1.add(po);

msg.setPoints(p1); publisher.publish(msg);

If I run the above code, the below message comes on Matlab and can’t publish.

No method 'setTimeFromStart' with matching signature found for class 'org.ros.internal.message.$Proxy27'.

Error in JointTraj (line 27) po.setTimeFromStart(1);

I would appreciate it very much if you could advise me anything.

Best regards,

Jun
