Matrix Lab
Drag matrices around in space until linear algebra clicks
Matrix Lab is a 56-level interactive course. You drag vectors, matrices, and grids on 2D and 3D canvases and watch determinants, eigenvectors, and basis changes happen under your cursor. First 7 levels free.
👏Hey everyone, Leo here. I'm the solo developer behind Matrix Lab.
I built this because of a specific frustration: every time I learned linear algebra from videos or textbooks, I could follow along, nod, and forget everything a week later. Watching someone else move vectors around never made the ideas stick for me.
So Matrix Lab has no videos. Each of the 56 levels is a small canvas experiment: drag a vector's tip to hit a target, stretch a column vector until the determinant hits zero, rotate a grid and watch the matrix columns move with it. The concept lands because your hand did it.
What's inside:
- 12 chapters, from "place your first vector" to eigenvectors, dot and cross products, and 3D space - A live matrix panel showing determinant, rank, and volume scale as you drag - A sandbox mode where you can edit any matrix and watch the space transform
The first 7 levels are free, no signup. The full course is a one-time $19.99, lifetime access, works on 2 devices.
