Is this supposed to work on Node.js? about eigen-js HOT 4 CLOSED

For sure! In a new folder, create a simple package.json file containing

{ "dependencies": { "eigen": "^0.2.2" } }

Create a file named test.mjs containing

`
// test.mjs
import eig from 'eigen';

(async () => {
await eig.ready;
let M = new eig.Matrix([[1, 2], [3, 4]]);
M.print("M");
M = M.inverse();
M.print("Minv");
eig.GC.flush();
})();
`

Now run yarn in that folder to install dependencies, and execute the test using node test.mjs

from eigen-js.

Yes, this worked now, but sometimes it breaks with the error TypeError: eigen_1.default.Matrix is not a constructor. I got this intermittently in an Observable notebook.

Maybe this is something related to asynchronous loading of the wasm?

from eigen-js.

Ah, I never tried it in that context. Not sure how Observable handles package loading...

from eigen-js.

I'm not saying this is just on Observable but in both contexts, this is an intermittent error that needs some debugging, maybe using async import() in typescript helps.
