R = rotx(ang), roty(ang), rotz(ang) is not working in my MATLAB.

R = rotx(ang), roty(ang), rotz(ang) is not working in my MATLAB. I get this error "Unrecognized function or variable 'rotx'." can anyone help me?

do we need extra tool box for this to be installed?

When I try the online MATLAB, there it works.

You need the Phase Array Toolbox, as noted here.

Answer 1

[Mike Croucher]

As Scott mentioned, these are in Phase Array Toolbox. Since you have access to it on MATLAB Online, it must be included in your license. As such, you should be able to install it using the MATLAB add ons Get and Manage Add-Ons - MATLAB & Simulink - MathWorks India

Not sure where I saw these coordinate transformation functions last but they where used to be called "rot1, rot2, rot3". And the code for them where in plain view. I am refering to installation disks issued by MathWorks prior to 2006. And they still work!
