Hi -
Over the last few years, I've started writing most of my Matlab code in packages. However, I don't seem to be able to search the help of these functions with lookfor, even if those functions are on the Matlab path.
Example: suppose a I have a package file:
+mypackage/mymfile.m
function y = mymfile(x)
% MYMFILE - performs a computation
%
% Y = MYMFILE(X)
%
% Returns the square of X.
%
y = x.^2;
If I type
lookfor computation
on the command line, mymfile is not found. How can I tell lookfor to search through my packages?
The behavior I expect is that it would return
mypackage.mymfile - performs a computation
(and the other matches on my workspace)
Thanks
Steve

Hi Steve,
I understand you would like to search within packages when using "lookfor". This feature is not currently available.
As an alternative, you can use the Function Browser. This is the "fx" button located just to the left of the prompt in the Command Window. You may also be able to do this using the “builddocsearchdb” function.

Thanks very much for looking! I'd really like a solution that one can use on the command line. Is it possible to turn this into a feature request for lookfor, or a similar command?
I think it really ought to be in lookfor, right? Isn't that where most people look for existing functions that may perform a task?
Thanks again for your help
Best
Steve
