Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  Passage: Matrix groups nwere matriks tinyere matrix multiplication. The general linear group GL ((n, R) nwere ihe niile nwere ike ịgbanwe agbanwe n-by-n matrices nwere ezigbo ntinye. A na-akpọ subgroups ya dị ka otu matrik ma ọ bụ otu linear. A pụrụ ile ihe atụ nke ìgwè dihedral a kpọtụrụ aha n'elu anya dị ka otu matrik (nke dị obere). Ndị ọzọ dị mkpa matriks otu bụ pụrụ iche orthogonal otu SO ((n). Ọ na-akọwa ntụgharị niile enwere ike n akụkụ. Site na Euler angles, a na-eji matrik rotation eme ihe n'ihe osise kọmputa. Ọ na-amụ otu ahụ site n'omume otu ahụ na oghere ndị ọzọ. Otu klas dị iche iche nke ihe nnọchianya nke otu bụ ihe nnọchianya nke ahịrị, ya bụ, ìgwè ahụ na-eme ihe na oghere vector, dị ka oghere Euclidean atọ-dimensional R3. Ihe ngosi nke G n'elu n-dimensional ezigbo vector ohere bụ nanị otu homomorphism  Ajụjụ: Olee otú size matriks otu nwere ike na-ahụ dị ka ihe atụ?
