Lineaarialgebrassa n×n-matriisia (eli neliömatriisia ) A sanotaan kääntyväksi, säännölliseksi tai epäsingulaariseksi jos on olemassa sellainen n×n-matriisi B, että A B = B A = I n {\displaystyle AB=BA=I_{n}\,} , missä In on n×n yksikkömatriisi ja kertolaskuna on matriisien tavallinen kertolasku.
In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate) if there exists an n-by-n square matrix B such that A B = B A = I n {\displaystyle \mathbf {AB} =\mathbf {BA} =\mathbf {I} _{n}\ } where In denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication.
