Showing algebraic loop ashow does not exist in Matlab 2017a?

Hi,

It is very strange that command ashow doesn't exist in Matlab 2017a but then I could find it is mentioned in the help. I am talking about the help when hitting F1 i.e. tight to this version, not online help. Any idea?? If it doesn't exist, what is the way to highlight algebraic loop?

Thanks,

Have you started the simulink debugger? https://www.mathworks.com/help/simulink/slref/ashow.html#mw_dfe2e39d-5d05-44d7-86ea-11c30db34efc

Yes. I started it and the error is

>> ashow

Undefined function or variable 'ashow'.

Did you mean:

>> sshow

The Simulink debugger shows as below
