Default_Path_Retrie​val

_________
This function can help if you:
- frequently access/write files/folders which are not necessarily on your MATLAB path

- Do lots of load/save type operations to various different destinations

- Use dialogue functions like uigetfile() and uigetdir()
_________

What it does:
If you have a path string in your current workspace, you can add it to a single database file.

At a later date, use a simple command to retrieve the path for reuse.

The database file is automatically created; there is no need to edit it manually.
_________

How I use it:
I write toolboxes. So in the toolbox I'm currently writing, users load image files, they load calibration files, and they load results files.

Each time uigetfile() is used to locate a file (of a given type), I use these functions to get the directory path of the last-accessed file of the required type. I pass this to the DefaultName input for uigetfile.

Result: The uigetfile() dialogue box goes to the most likely folder in which that file type is stored, instead of starting in the MATLAB current directory.
