msginfo = rosmsg("show", msgtype)
msgmd5 = rosmsg("md5", msgtype)
msglist = rosmsg("list")

Description

rosmsg showmsgtypereturns the definition of themsgtypemessage.

rosmsg md5msgtypereturns the MD5 checksum of themsgtypemessage.

rosmsg listreturns all available message types that you can use in MATLAB®.

example

msginfo= rosmsg("show",msgtype)returns the definition of themsgtypemessage as a character vector.

example

msgmd5= rosmsg("md5",msgtype)returns the ‘MD5’ checksum of themsgtypemessage as a character vector.

msglist= rosmsg("list")returns a cell array containing all available message types that you can use in MATLAB.

ROS message type, specified as a character vector.msgTypemust be a valid ROS message type from ROS that MATLAB supports.

Example:"std_msgs/Int8"

Output Arguments

Details of the information inside the ROS message definition, returned as a character vector.

MD5 checksum hash value, returned as a character vector. The MD5 output is a character vector representation of the 16-byte hash value that follows the MD5 standard.

List of all message types available in MATLAB, returned as a cell array of character vectors.
