The Pseudoinverse of $A = C R$ is $A^{+} = R^{+} C^{+}$ (?)

Michał P. Karpowicz, Gilbert Strang

This paper gives three formulas for the pseudoinverse of a matrix product $A = C R$ . The first is sometimes correct, the second is always correct, and the third is almost never corr…

Elimination and Factorization

Gilbert Strang

If a matrix $A$ has rank $r$ , then its row echelon form (from elimination) contains the identity matrix in its first $r$ independent columns. How do we \emph{interpret the matrix}…

A Neural Network Solves, Explains, and Generates University Math Problems by Program Synthesis and Few-Shot Learning at Human Level

Iddo Drori, Sarah Zhang, Reece Shuttleworth +15

We demonstrate that a neural network pre-trained on text and fine-tuned on code solves mathematics course problems, explains solutions, and generates new questions at a human level…

A Local Inverse Formula and a Factorization

Gilbert Strang, Shev MacNamara

When a matrix has a banded inverse there is a remarkable formula that quickly computes that inverse, using only local information in the original matrix. This local inverse formula…
