MATLAB Central Newsreader - Create setup m-file

Create setup m-file

Samb1985 — Thu, 30 Jul 2009 14:00:19 -0400

I would like to create a m-file (setup.m), that will be located in the default matlab directory.
When I execute "setup" it must find on the pc a folder "MyApp" and add its path with all its subfolders to matlab search path, so I can run my matlab application without going on File - Set Path men?.

It is possible ? how ?

Thanks in advance.

Why not just add your folder to the path once and for all? There is no need to do it every time. Go to File>Set Path

Matt has answered one aspect of your post, but another is that if you
create a file called startup.m and put it in the Matlab work
directory, that file will be executed everytime you run Matlab.
I have lots of stuff in my startup.m, including: cd to my Matlab
directory, default plotting options, setting random seeds, warning
off's, etc.

I need to use the application in different Pc, so in different directory in each PC.
So I'm searching for a method that allow me to add the paths of application with a single command.
Otherwise i need to create different startup.m or pathdef.m for the different PC, that is the thing that I would like to automate.

I see the function addpath but i need to know the path of the folder. First i need to search the folder on the PC.

So, you've put MyApps in some obscure place on your PC, and now you
can't find it.
Why is this a Matlab problem?

A better strategy would be to note where you put MyApps, and use
addpath to point Matlab to it.

well, derek, we both realize: its an early sign of an insidious, neurodegenerative disease (aka dementia) - and, therefore, CSSMers have to be particularly patient and forgiving...

You can define an environment variable on your system that contains the path to MyApp. Then, you edit startup.m such that it recursively runs addpath.m on that directory.

Alternatively, you can use userpath.m to change the startup directory.

This is what STARTUP.M is supposed to do.

If I use startup i need to know the path where MyApp is located. If i don't know it and i want to search and add it automatically ? i think it is impossible, so i will search for another solution.
