Details:

I think the mex function mexPutVariable is not working correctly, specifically
when the desired workspace is set to "caller" and the mex file is called from
within a function. If an mxArray is passed to the "caller" workspace from
mexPutVariable, it is actually passed to one level above the caller.

In the attached example, the mex source file simple_array.c creates an array
to pass to the caller's workspace. If compiled using: "mkoctfile --mex
simple_array.c" and executed: "simple_array" from the command line, the
variable out_caller appears in the workspace as expected, verified using
"whos". 

However, if the mex file is called within a m-file function(see run_me.m),
then the variable is not pased to the caller, but to the base workspace. This
can be seen in the attached run_me.m file. I expect to see the who list called
in run_me.m to return OUT_caller.

command line calls in order:
mkoctfile --mex simple_array.c
run_me
%whos output shows nothin in run_me workspace.
whos
%output from comand line shows variable out_caller
