help in R2022a

When typing 'help functionname' in R2022a I no longer get all the commented text at the beginning of a function, as I was used to in my older version of Matlab. How can I restore this function? Now I just get 'functionname is a function' and an example 'output = functionname(input)'

It should work but I never use it. I use doc instead:

>> doc functionname

doc opens up the help window, unlike help, which has the advantage that there is a lot more information, including a "see also" section at the bottom where you can learn about related functions.

[Rogier Mars]

Yes, but is there a way to make 'help' work in the old way again? I don't like 'doc', because it just leads to more pop-up windows.

[Rogier Mars]

Oh, and interestingly, 'doc' shows the same behavior.

experiment with

restoredefaultpath; rehash toolboxcache

to see if that temporarily fixes the problem
