Find the help for sim command in the MPC Toolbox

The sim command can be used to simulate Simulink models or MPC objects. How can I open the Help Browser from the command line for the sim in the MPC Toolbox? The "doc sim" command open the reference for Simulink sim, not MPC sim.

I could use the "doc mpc/sim" command in the past to get help from the command line for the MPC sim. It doesn't seem to work in R2018b.

help mpc/sim is able to pull the help page for mpc sim command while doc mpc/sim can't

There seems to exist a consistency issue.

• In R2018a, "doc mpc/sim" brings up the correct doc page. The address is

web(fullfile(docroot, 'mpc/ref/sim.html'))

• In R2018b, "doc mpc/sim" WON'T bring up the correct doc page. Using address can bring it up

web(fullfile(docroot, 'mpc/ref/sim.html'))

• In R2019a, "doc mpc/sim" brings up the correct doc page. The address is slightly different

web(fullfile(docroot, 'mpc/ref/mpc.sim.html'))

I would add that "doc mpc/sim" also works in R2019b. So R2018b is the only version that doesn't work.

How did you find out the corresponding web commands?
