what happens when you load a directory?

Question

I am trying to learn some simple matlab code posted by my professor, and the first line goes somehting like

load /class/mat121/lab1/data

I've never seen "load" used like this before, what does it do? does it load all .m files in the directory?

I also see a lot of custom functions in the code, such as "T()", "Lon()", "Lat()" etc, they aren't standard matlab functions therefore I am assuming they are imported from that directory?

thanks

Please split multiple questions in different questions. – EwyynTomato Mar 17 '12 at 03:00 — EwyynTomato, Mar 17 '12 at 03:00

Title is incorrect, because "data" is not directory.

You can refer to load function.

Anyway,

/class/mat121/lab1/

this should be the directory path

data

this should be a file called "data.mat" which contains matlab workspace variable that is previously saved with save function.

So,

load /class/mat121/lab1/data

loads workspace variables from "data.mat" which is located under "/class/mat121/lab1/".

@EwynnTomato is correct. `load()` is for retrieving MATLAB-formatted data from a file. – Li-aung Yip Mar 17 '12 at 03:43

If you have access to matlab, the best thing to do would be to run the following commands and have a look at the results:

help load
help which
which T
help T
which Lon
which Lat

Running these commands should tell you:

What Load does
What which does
Where T is
What T does
Where Lon is
Where Lat is

what happens when you load a directory?
