I need help from Matlab users..my question is.. how to solve Undefined function or method 'robot.m' for input arguments of type 'double'?? what is type 'double' in the simulation diagnostics?? please help me..tq.

Hi, your problem is that MATLAB doesn't know where the file robot.m is. If you have this file saved somewhere on your computer, you have to make sure that directory is in MATLAB's path. See >>doc addpath >>doc path double here is just the class of your input, it's saying basically: "hey, you want me to take this input with class double and do something to it with a function or method robot, but I have no idea what robot is."
