I am trying to use the equivalent to np.linalg.norm (which works fine locally) to Javascript. I’m not super familiar with JS but as far as I can tell, Math.norm is an existing function, although it throws an error when I try to use it. This is how I call it:
r = Math.norm(mouse_resp_1.getPos());
Am I incorrectly using it, do I have to separately download the math library, or is there some other issue?
Edit: The error is: TypeError: Math.floor() is not a function
TypeError: Math.norm() is not a function
Math is a built in function that doesn’t have norm
math isn’t built in but does contain norm. Just in case, you could try math.norm() but I suspect is isn’t available.

Interesting, I use other math functions (sin, cos, etc.) and they work, so I assumed the math library was built in. Maybe they are just part of PsychoJS?

Math is built in
math may not be
I see what you mean now! You’re right, math does not seem to be built in.
I’ve solved it by adding
to my index.html file.
Thank you @wakecarter for pointing me in the right direction!

I haven’t edited index.html before. Exactly what line did you need to add to be able to use math?
There is an external libraries section:
