## What it is
A collection of graphic notes and visual diagrams explaining linear algebra concepts from Gilbert Strang's 'Linear Algebra for Everyone'. It provides intuitive visualizations of matrix factorizations like LU, QR, eigenvalue decomposition, and SVD, distributed as PDF documents.

## Use cases
- learn linear algebra visually
- understand matrix factorizations like LU, QR, and SVD
- supplement study of Gilbert Strang's Linear Algebra for Everyone
- find intuitive visualizations of eigenvalues and diagonalization
- teach linear algebra concepts with diagrams
- review vector and matrix calculations graphically

## When to choose
- you want visual, intuitive explanations of linear algebra concepts
- you are studying Strang's textbook and need supplementary graphics
- you prefer diagrams over dense mathematical proofs
- you need free, openly licensed educational material on matrix factorizations

## When to avoid
- you need rigorous proofs or a complete linear algebra textbook
- you need interactive software or computational tools rather than static notes
- you need practice problems or exercises

## Facets
- artifact type: learning-resource
- maturity: active
- function: data-visualization, documentation
- domain: mathematics, education, tutorials
- platform: cross-platform
- tags: linear-algebra, visual-notes, gilbert-strang, matrix-factorizations, pdf
