evalin('ca​ller','mfi​lename') does not work.

function out = cdc
out = evalin('caller','mfilename');
end

This fucntion returns the 'cdc', not the caller's mfilename.

Why don't you use mfilename directly in the caller? Alternatively you can do something similar with dbstack.

dbstack does not five the full path to the function.

Now I have used mfilename in caller. I'm just curious about how the mfilename works.

Depending on your release you can get the complete names including the path from dbstack (in v6.5 you couldn't, but already since v7.0 you can). As the doc describes:

dbstack(___, '-completenames') 
outputs the fully qualified name of each function in the stack.

Answer 2

[Walter Roberson]

"evalin('caller', expression) finds only variables in the caller's workspace; it does not find functions in the caller. For this reason, you cannot use evalin to construct a handle to a function that is defined in the caller."

If I recall correctly mfilename is implemented by defining a function in each file.
