How do I choose which CarSim database to run off of in MATLAB?

I am currently working on an implementation of CarSim and MATLAB. I am using multiple databases and need to know if there's a way to programmatically set the database to use in MATLAB. I have had very little luck finding documentation for CarSim integration in MATLAB, so if someone has a source for that, that would additionally be much appreciated.

Hey Maxwell,

Some quick pointers that might help you :

CarSim databases are typically selected via the CarSim GUI, but you can influence which database is used in MATLAB by:

• Setting the working directory: CarSim uses the current working directory to locate the database files. You can set this in MATLAB using:

cd('C:\Path\To\Your\CarSim\Database') 

• Using environment variables: Some setups rely on environment variables like VS_ROOT or VS_DATABASE to locate the database. You can set these in MATLAB using:

setenv('VS_ROOT', 'C:\Path\To\Your\CarSim') 
setenv('VS_DATABASE', 'C:\Path\To\Your\CarSim\Database') 

• Calling CarSim from MATLAB: If you're using the VehicleSim API (VS API), you can initialize the simulation with a specific database path using the vs_load or similar functions provided in the SDK.

Here are the official MathWorks documentation and resources that support CarSim integration with MATLAB and the use of environment variables:
