MATLAB: Finding operating points w. R2012b

Question

Are the functions "findop", "linearize", and 'operspec" still supported in R2012b? They are discussed in the documentation, but when I ask for help on them using the MATLAB command line it says the functions cannot be found. (I do have the Control System Toolbox.) And if these functions are no longer available, how does one find operating points for a non-linear Simulink simulation?

I have used "trim" with limited success, so I need a better technique.

Answer 1

I believe the functions you mention are part of a product called Simulink Control Design (different from control systems toolbox).

This is listed under Simulink Product Family: http://www.mathworks.com/products/
