create a script to change directory in matlab

To change the current directory using a MATLAB script, you can use the cd function. Here's an example:

main.m
newDirectory = 'C:\my\new\directory';
cd(newDirectory);
56 chars
3 lines

Replace C:\my\new\directory with the path to the directory that you want to navigate to.

Note that changing directories within a script only affects the current MATLAB session. If you want to change directories permanently, you'll need to modify your MATLAB startup settings.
