Complex.js VS mathjs

The background for this is that I'm using Node-RED to acquire data from a .csv file. Then, I am transferring it to a database where before that I would need to flip the time trace to the frequency domain via a pwelch. That way I can store the time trace and the frequency domain data. Currently what I am doing is using the Complex.js library found here: https://github.com/infusion/Complex.js. After that, I just use a very simple DTFT to get the frequency domain. However, I want to add some overlapping, window length and zero padding to my transformation, and this is where I think it would be easier to just a pwelch. I'm wondering if there is an simple way of implementing this. Otherwise I would have to have to look into a window library and create some sort of overlap using DTFT or another fourier transform technique.

The Math blocks are powered by Math.js (https://mathjs.org/).

math.js is a comprehensive JavaScript library that offers support for working with matrices and multidimensional arrays. It contains a huge array of mathematical functions in addition to array operations, making it suitable for a wide range of mathematical activities.

ii) Third-Party Libraries There are various libraries like math.js, decimal.js, big.js that solve the problem. Each library functions according to its documentation. This approach is comparatively better.

mathjs integration. Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices. Is compatible with JavaScript’s built-in Math library. Contains a flexible expression parser. Does symbolic computation. Comes with a large set of built-in functions and constants.

hey, this looks interesting. there is library, mathjs , that is providing pretty printing , which I'm looking for.

It's because it's not supported out of the box by the mathjs library I'm using: https://mathjs.org/

I agree that this would be nice.

Ha, yes, I was being nosy. It was quite easy to spot as it's the only XHR/Fetch request.

I was intrigued what you had used to build it, and if you had built your own solver (which you have), and what editor you used (Code Mirror) so went looking at the code. Interesting to see you left the source maps for production, made it easy for my sleuthing...

I experimented with a similar idea last year, but used ProseMirror/TipTap as the editor to enable rich text editing, and the MathJS (https://mathjs.org) solver. I also combined it with PouchDB and Yjs for offline editing and syncing between devices. Never finished it though, you have kept your nice and simple!

This is nice but I believe something much better can be achieved using JavaScript, in particular math.js.

I also found this math input library: http://mathquill.com/ , and https://mathjs.org/ seems to contain code for solving math problems.

What about math.js? It has an expression parser that looks pretty nice.
