          /line    51 msgs  : geometry_msgs/Point

Create a rosbagreader object of all the messages in the rosbag log file.

reader = rosbagreader('path_record.bag');

Select all the messages related to the topic '/circle'.

bagSelCircle = select(reader,'Topic','/circle');

Retrieve the list of timestamps from the topic.

timeStamps = bagSelCircle.MessageList.Time;

Retrieve the messages in the selection as a cell array.

messages = readMessages(bagSelCircle);

Create a rosbagwriter object to write the messages to a new rosbag file.

circleWriter = rosbagwriter('circular_path_record.bag');

Write all the messages related to the topic '/circle' to the new rosbag file.

write(circleWriter,'/circle',timeStamps,messages);

Remove the rosbagwriter object from memory and clear the associated object.

delete(circleWriter)
clear circleWriter

Retrieve all the information from the new rosbag log file.

Load the new rosbag log file.

readerCircle = rosbagreader('circular_path_record.bag');

Create a time series for the coordinates.

tsCircle = timeseries(readerCircle,'X','Y');

Plot the coordinates.

plot(tsCircle.Data(:,1),tsCircle.Data(:,2))
axis equal

Figure contains an axes object. The axes object contains an object of type line.

`bagwriter` — ROS log file writer
`rosbagwriter` object

ROS log file writer, specified as a rosbagwriter object.

`topic` — ROS topic name
string scalar | character vector | cell array of string scalars | cell array of character vectors

ROS topic name, specified as a string scalar, character vector, cell array of string scalars, or cell array of character vectors. Specify multiple topic names by using a cell array.

Example: "/odom"

Example: {"/odom","cmd_vel"}

`timestamp` — Timestamp of ROS message
