Simple question about defining function

I have a function like this:

function funs = test

funs.er=@er;

...

end

What that syntax means? My question is: How can I call "er" from funs?

I think this answers your query best - https://www.mathworks.com/matlabcentral/answers/440767-how-do-i-call-a-function-within-another-function.

So, to call a function "er" from "funs", you can simply call it like:

er()

or

y=er(), if 'er' has a return value.

The syntax "@er" returns a handle to the 'er' function, which can be used in functions like 'integral,' etc.
