Undefined function or variable 'createRigidBodyTree'.

I have the Robotics System Toolbox installed but this error shows up when I try to use this line of code

robot = createRigidBodyTree ;

[勇刚 张]

'createRigidBodyTree'可能是一个.m文件，并不是一个可以直接使用的函数，直接使用的函数是rigidBodyTree

Hello Tasneem,

"createRigidBodyTree" is not a function that ships with RST, or any MATLAB toolbox as far as I can tell. It appears to be part of a file-exchange submission designed to demonstrate some of the robotics-related capability. Did you have a previous version of MATLAB that this worked with, and now that you have installed R2018b it no longer works? If that is the case, you may simply need to add the folders back to the MATLAB search path again.

Alternatively, you can construct a rigid body tree using the normal constructor.
