l-ask matlab in javascript

To ask MATLAB in JavaScript, you can use the matlab-engine npm package. Here is an example code snippet where we can ask MATLAB to generate a random number:

index.tsx
const matlab = require('matlab-engine');

(async () => {
  let eng;
  try {
    eng = await matlab.start();
    const randomNum = await eng.eval("rand(1)");
    console.log(`Random number generated from MATLAB: ${randomNum}`);
  } catch (err) {
    console.error(err);
  } finally {
    if (eng) eng.close();
  }
})();

In this example, we first import the matlab-engine module. Then we create an asynchronous function to start the MATLAB engine. Once the engine is started, we can use eng.eval method to evaluate MATLAB code. In this case, we are generating a random number using MATLAB's rand function. Finally, we print the generated random number to the console.

Note that this only demonstrates a basic usage of the matlab-engine package. For more complex use cases, you will need to refer to the documentation.
