View on Github →chore(Data/Matrix): split Basic.lean into Defs.lean and Mul.lean (#18972)
This is based on noticing that the definition of Matrix imports Algebra.
Defs.leancontains the definition of theMatrixtype and its module structureMul.leancontains vector-and-matrix multiplication operatorsBasic.leanstill contains bundled versions of the operations defined above, and a few lemmas that didn't fit anywhere else.
