set up a bvar model in matlab in javascript

To set up a bvar model in Matlab using JavaScript, you can follow these steps:

1. Create a Matlab script file with the necessary commands to set up the bvar model. For example:

main.m
% Set up the bvar model
bvar_model = bvar('VAROrder', 2, 'SeriesNames', {'Y1', 'Y2', 'Y3'});

3 lines

2. Save the script file with a ".m" file extension.

3. Use the engEvalString function in the matlab.engine package in JavaScript to run the script file in Matlab from your JavaScript code. For example:

index.tsx
const { MatlabEngine } = require('matlab-engine');
const engine = await MatlabEngine.start();

// Run the Matlab script file
await engine.engEvalString('run my_bvar_script.m');

...

Note that you'll need to have the matlab-engine package installed and configured properly for this to work.

4. Once the bvar model is set up in Matlab, you can use the Matlab Engine API in JavaScript to interact with it and perform calculations. For example:

index.tsx
// Get the bvar model's posterior mean
const mean_val = await engine.getVariable('bvar_model.PosteriorMean');
console.log(mean_val);
