            Finding Null Space of Matrix in Javascript
            Asked 2022-Jan-29 at 22:22

            I am wanting to see how I can find the nullspace of a m x n matrix in javascript. In MATLAB, we can use the built-in function null(A). So I was wondering if there is something similar for javascript? I know that we could try solving the system Ax=0, but using the math.js libraries, the built-in functions come with the requirement that A is n x n or square. Which is not necessarily the case.

            See for example https://mathjs.org/docs/reference/functions/lusolve.html

            I'd appreciate any references to do this in javascript or how I could build such a script from scratch if needed.

            Thanks!

            Wanting to restrict to just what's in math.js...

            If you know m > n and A has full column rank and your need is just to see what part of some m-dimensional vector v is not in the column span, then math.qr and do v - (Q' * (Q * v))

            Otherwise, try math.eigs on A' * A and then pick the eigenvectors corresponding to the nearly-0 eigenvalues (according to some tolerance).

            How can I add "deg" after all numbers in trig functions?
            Asked 2022-Jan-13 at 18:19

            I'm using Node.js with the mathjs package. Mathjs uses radians in its trig functions. I want to include a degree mode for a calculator I'm making. How can I add "deg" after every number within any sin/cos/tan function in a string? This way, mathjs will calculate it using degrees instead so it can work.

            Example: 5*(2+3)/sin(4+(3-2)) should become 5*(2+3)/sin(4deg+(3deg-2deg)) However: 5*(2+3)/(4+(3-2)) should not change.

            I've looked everywhere: Regular expressions, reddit, google, I've found nothing. The closest I've come is a regular expression that breaks when there are parentheses inside the sin function (/sin\(.*?\)/).

            Edit: Yes I have looked at the angle configuration example. No, that doesn't solve my problem: It assumes the user is implementing a single value to calculate the sine of, I am trying to calculate full expressions with a degree mode (mathjs.evaluate())

            You could instead simply replace the trig function implementations with versions that use degrees...

            Look at the angle configuration example in the MathJS docs. You can use the math.import function to provide your own function implementations for sin, cos, etc., and you can refer to the original ones by first saving a reference to them.

            ANSWER

            Answered 2021-Nov-01 at 04:56

            Your package.json has a mix of dev dependencies with versions that start with ~ and ones that start with ^. That's probably because some dev dependencies were installed with older versions of npm that defaulted to ~ which is more conservative than ^. As a first step, change the 8 ~ versions to ^, remove node_modules and (if it exists) package-lock.json and run npm install again. I tested this locally and it didn't reduce the number of vulnerabilities reported by npm audit but it did reduce the number of outdated packages which is a step in the right direction.

            Let's simplify things by only looking at the audit results for your production dependencies and ignoring (at least for the moment) issues in your dev dependencies. npm audit --only=prod reports only 5 issues, all moderate. Running npm audit --only=prod --force fix updates @capacitor/cli from 2.x to 3.x. That's a breaking change so you'll want to test it, but if that works for you, congratulations because npm audit --only=prod reports no vulnerabilities.

            At this point, you could possibly choose not to worry much about the other issues reported by npm audit. However if you wanted to fix them, here is the potentially tedious/arduous path I'd recommend:

            • Do a manual audit of all of your dev dependencies to make sure you aren't including things you don't need. Maybe you have things that are installed that you aren't using. Uninstall them. Maybe you have things installed that are nice-to-have but you don't really need. Consider uninstalling them too.
            • Run npm outdated to see what could be manually updated via a breaking change. Try doing those updates.

            Solving non-square system of linear equations in Javascript
            Asked 2021-Jul-11 at 02:02

            I have a system of resistors, something like this: Resistor schematic

            I made a website which renders diagrams like this one (not this one exactly). The user can change resistance of each resistor. I want to calculate every current in the system.

            I found a solution using Kirchhoff's laws, which gave me a system of linear equations. I solved it with math.js using inverse matrix. This approach worked well on smaller circuits.

            In this circuit, i have more equations, than variables, which means that I cannot compute inverse matrix, to solve them. Simplifying them manually, to match the number of unknowns is an option, but that would require a human. The website should be able to calculate everything on its own.

            Now I am looking for a way to solve a system of linear equations, which cannot be represented as a square matrix. Any suggestions?

            Thanx!

            • This approcah makes a row reduction of the matrix, and gives as a result an string with the unknown values. In case the system has infinite resolutions, this would returns simplified equations so you can parameterize later.
