Option `errorTolerance` is misnamed and theoretically wrong

8

As can be seen in [index.js](https://github.com/mljs/levenberg-marquardt/blob/master/src/index.js#L63) and [errorCalculation.js](https://github.com/mljs/levenberg-marquardt/blob/master/src/errorCalculation.js#L18), the option named `errorTolerance` is there to stop the program after the sum of absolute values of residuals drops below some critical...

Errors in variables?

6

I need to fit data points with errors in both variables. Does a "weighted" version of this algorithm exist? Would it be viable to implement it? I've spent hours searching...

[FEATURE] Add more fields to the `package.json` documentation

6

When creating JS libraries, the [`package.json` documentation](https://docs.npmjs.com/cli/v7/configuring-npm/package-json) on docs.npmjs.com is one of the most helpful resources to me. However it is far from complete, there are many fields that aren't...

Implement symbols for CAS computations

10

Advanced CAS systems let users define their own symbols and perform symbolic operations with them. [Example in Sympy.](https://docs.sympy.org/latest/tutorial/basic_operations.html) Since all math.js functions can operate on complex numbers (that means they...

Add methods for iteration of matrix rows and columns

2

Right now there is no comfortable way of doing something like this: ```typescript const mat = matrix([ ... ]) for (const col of mat.columns()) { console.log("here's a column: ", col)...

Add a function that only finds eigenvalues, not eigenvectors

4

The current implementation of `eigs` for complex matrices (see PR #1743) starts with finding eigenvalues and then proceeds to find eigenvectors. Since not everybody needs eigenvectors, a significant portion of...

Implement eigenvalue estimation for eigs

1

The current eigenvalue algorithm supports [shifting](https://math.stackexchange.com/q/3928328/) however as of now it is not used. The gist of shifting is this: 1. The smaller (the absolute value of) the eigenvalue, the...

Automatically generate type definitions

1

I know that this repository is JavaScript by choice and I'm definitely not proposing to rewrite it in TypeScript. However, most modern IDEs leverage type definitions to show tooltips and...

Add a simple way to do operations with equations

16

#### References to other Issues or PRs Could be a very light-weight alternative to #17097. Compatible with #18053 Fixes #5031. #### Brief description of what is fixed or changed One...

Inferred recursive types

3

I'm working on a library that needs type definitions at runtime, and I wanted to use Zod as it's the _“lingua franca”_ of runtime type definitions. However, my library will...
