MATLAB: Rotz cannot be called

Question

Hi,

I tried to do a rotation matrix about z-axis. Somehow it cannot recognize it.

theta = 10;

rotz(theta);

There is error – Undefined function 'rotz' for input arguments of type 'double'.

It is furious. Does anyone know how to solve it?

Thanks.

Answer 1

rotz() is part of the Phased Array Toolbox. You would need to have it installed.

Alternately you could use rotz from a File Exchange contribution. Note though that rotz() from the Phased Array Toolbox works in degrees but the File Exchange contribution works in radians.
