About

MatrixLab

Linear algebra powers machine learning, graphics, and AI — yet courses often reduce it to symbol manipulation. Students memorize determinant formulas and eigenvalue algorithms without seeing what they mean geometrically. MatrixLab makes learning interactive: touch the math, and watch space, images, and performance respond in real time. Four Progressive Labs L1 · Geometry Lab — Drag basis vectors î and ĵ to warp the coordinate grid. See determinants, area scaling, reflections, and singular transforms as geometry you create. L2 · Linear Algebra Lab — Explore eigenvalues, Jordan normal form, similarity and congruence transforms, and 3D quadric surfaces from symmetric matrices. L3 · Image Filter Workshop — Edit convolution kernels and filter patterns, gradients, checkerboards, or your own photos. Presets include edge detection, sharpen, blur, and Sobel — or invent your own. L4 · Performance Engine — Animate CPU cache behavior and blocked matrix multiplication. See how memory layout drives hit rates and real-world speed. Challenges & Progress — Hands-on challenges in each lab with local progress tracking.

Lumenfold

Lumenfold er et skrivebord til den, der regner. Det er til matematikere og til folk, der læser fysik, fordi de har lyst. Ikke et kursus og ikke en chatbot. Bord • Dagens margen skifter med datoen og regner selv sit udtryk • Seneste resultat ligger klar, så du kan regne videre Regner • Udtryk med potens, fakultet, rødder og trigonometri • Komma eller punktum som decimal, semikolon mellem argumenter • Radianer eller grader. Hyperbolske funktioner følger ikke vinklen • Dobbelt præcision. Det, du ser, er afrundet Kurve • Tegn f(x), og læg eventuelt g(x) ovenpå • Træk, knib, tryk for at aflæse. Kurven regner altid i radianer Bænk • Pendul, kast og fjeder uden luftmodstand • Pendulet følger sin θ. Den korte formel vises ved siden af, og appen siger til, når den ikke længere passer • Tyngde for København, standard og Månen Arkiv • Enheder, og konstanter hvor de eksakte i SI er mærket • Feltbog, talrække og syntaks • Alt gemmes i en fil på telefonen

Verdict

The call

MatrixLab and Lumenfold are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
