How can I change the DEFAULT line thickness on a control systems toolbox function (rlocus, bode, step, lsim, etc..)?

I have been successful to change the default line thickness of all my plot() command by using the

set(0,'defaultlinelinewidth',2)

command on a startup.m file inside the ../toolbox/local directory.

However it looks like plots generated by the rlocus, step, slim, or any control system predefined function does not get affected by it.

It would be wonderful if I could add another line at startup.m that I can change the default line thickness, and font sizes for my control system graphs.

thank you for your help,

already looked at: http://somemanuals.com/THE--MATHWORKS,CONTROLSYSTEM--TOOLBOX--9,HIIFHHI.PDF

have only found a graphical way to do this but there is no options for linewidth

set(findall(gcf,'type','line'),'linewidth',3);

Please use-set(findall(gcf,'type','line'),'linewidth',3);

That was the one! Thank you!

Currently there is no documented programmatic way of doing this. I have created an enhancement request for this functionality.

Had a look at the program code of the plotting function today, still not possible. :-(

For Bode-plots and the like, LineWidth is invisibly and unchangeably hard coded in the constructor of 'wavepack.wavestyle' which gets instantiated in controllib\graphics\@wavepack\@WaveStyleManager\makestyles.m

I've tried changing the for-loop to include a line

 style(ct).LineWidth = 2

but it gets ignored unfortunately. If you set a breakpoint and type the command on the command line then it works...

I've also tried putting the class files elsewhere and masking the path as someone suggested in https://ch.mathworks.com/matlabcentral/newsreader/view_thread/138604 but this doesn't work either. So I'm stuck as well...
