Hi, Thank you for your reply.
I just run SLAM with ROS and used "rosbag record -a" for recording the data, and then used the bag data in MATLAB with the following code:

a=rosbag('bag file name')
b=select(a, 'Time',[a.StartTime a.EndTime], 'Topic', '/scan');
c=readMessages(b);
(and for odometry i used \odom)
P.s--> timing between odometry and scan data was not the same so I catched the odometry data every five step and ignored the rest..

I think that the frame_id of the scan data in rosbag file is "base_scan".
Could you make new rosbag file?
Change the frame_id from "base_scan" to "odom".
