Gather, GatherBy — gather equivalent elements into sublists

DeleteDuplicates ▪ SplitBy

Ratios — find successive ratios of elements in a list

Matrix Construction

IdentityMatrix, DiagonalMatrix (modified) — create rectangular matrices

ConstantArray (modified) ▪ PauliMatrix ▪ LeviCivitaTensor ▪ UnitVector

CrossMatrix ▪ DiamondMatrix ▪ DiskMatrix ▪ BoxMatrix

Operations on Matrices

ArrayPad — add padding of many types to an array in any number of dimensions

UpperTriangularize, LowerTriangularize — extract parts of a matrix

SymmetricMatrixQ — test whether given matrix is symmetric

SchurDecomposition (modified) ▪ RealBlockDiagonalForm (modified)
