Hello Everyone I am having problem while using rotm2eul command in matlab. It gives an error stating "Undefined function 'rotm2eul' for input arguments of type 'double'." Can anyone help me real quick. Thanks.

When I enter these two lines in command window I get an error as stated above

rotm = [0 0 1; 0 -1 0; -1 0 0];
eulZYZ = rotm2eul(rotm)

Either you don't have Robotics System Toolbox or a valid license for it.

>> help rotm2eul
'rotm2eul' requires Robotics System Toolbox.

To check it:

ver % to check if you have that toolbox
license('test','Robotics_System_Toolbox') % to check if you have valid license (returns logical)

It returns this

MATLAB Version: 9.2.0.538062 (R2017a)
MATLAB License Number: FreeForAll
Operating System: Microsoft Windows 8.1 Pro Version 6.3 (Build 9600)
Java Version: Java 1.7.0_60-b19 with Oracle Corporation Java HotSpot(TM) 64-Bit Server VM mixed mode

and the answer to license('test','Robotics_System_Toolbox') is 0

So you don't have license for Robotics System Toolbox , get a valid license and then download it.
