LU Factorization
From the book
Chapter 5: Square Matrix and LU Decomposition. In the chapter mind map this icon labels $A = LU$. The discussion below is excerpted and lightly edited from § Opening in Mathematics for AI and Machine Learning.
Square matrices: triangular matrices, trace, determinants, and LU decomposition with variants and extensions
What this drawing shows
