Ma kēia paʻi ʻana, e noʻonoʻo mākou i ke ʻano o ka matrix minor, pehea e ʻike ʻia ai, a me ka nānā ʻana i kahi laʻana e hoʻohui i nā mea theoretical.
ʻO ka wehewehe liʻiliʻi matrix
Nā hana Mij i ʻeleʻele aij ka mea hooholo n-ʻo ke kauoha ka mea hoʻoholo (N-1)-th kauoha, i loaa ma ka holoi ana i ka laina i a me ke kolamu j mai kumu mai.
kumu o kapa ʻia kekahi mea ʻuʻuku ʻole ʻole o ka matrix o ka ʻoi loa. ʻO kēlā mau. i ka matrix A kauoha ʻuʻuku r he kumu inā ʻaʻole like ia me ka ʻole, a me nā keiki liʻiliʻi a pau r+1 a ma luna aʻe he zero a ʻaʻole paha. Ma kēia ʻano, r pili i ka liʻiliʻi o nā waiwai m or n.
He laʻana o ka loaʻa ʻana o kahi keiki liʻiliʻi
E ʻimi kāua i kahi keiki liʻiliʻi M32 i ʻeleʻele a32 mea wehewehe ma lalo:
pāʻoihana
E like me ka hana, pono mākou e holoi i ka lālani ʻekolu a me ke kolamu ʻelua mai ka mea hoʻoholo:
Loaʻa iā mākou kēia hopena:
No ka mea hoʻoholo like ʻole M13 i ʻeleʻele a13 me he mea la:
