Ma kēia paʻi ʻana, e noʻonoʻo mākou i ke ʻano o nā matrices, e hele pū me lākou me nā hiʻohiʻona kūpono e hōʻike ai i nā mea manaʻo i hōʻike ʻia.
Hoʻomanaʻo i kēlā Ke kumu – He ʻano papa ʻāʻī kēia me nā kolamu a me nā lālani i hoʻopiha ʻia me kekahi mau mea.
Nā ʻano matrices
1. Ina hookahi lalani ka matrix, ua kapaia line vector (a i ʻole lālani matrix).
la'ana:
2. Ua kapa ʻia ka matrix me hoʻokahi kolamu kolamu vector (a i ʻole matrix-column).
la'ana:
3. pāhoʻonui he matrix i loaʻa ka helu like o nā lālani a me nā kolamu, ʻo ia hoʻi m (nā kaula) like n (nā kolamu). Hiki ke hāʻawi ʻia ka nui o ka matrix n x n or m x mkahi m (n) – kāna kauoha.
la'ana:
4. ʻole he matrix, ua like na mea a pau me ka nul (aij = 0).
la'ana:
5. Ka diagonal He matrix huinaha like ia me na mea a pau, koe na mea e waiho ana ma ka diagonal nui, ua like ia me ka ale. He triangular luna a me lalo i ka manawa like.
la'ana:
6. Single He ʻano o ka diagonal matrix i like nā mea a pau o ka diagonal nui me ka hoʻokahi. Hōʻike pinepine ʻia e ka leka E.
la'ana:
7. huikolu luna – ua like nā mea a pau o ka matrix ma lalo o ka diagonal nui me ka ʻole.
la'ana:
8. huinakolu haahaa he matrix, ua like na mea a pau me ka zero maluna o ka diagonal nui.
la'ana:
9. hana ʻia He matrix i hoʻokō ʻia nā kūlana penei:
- inā he lālani null i loko o ka matrix, he null nā lālani ʻē aʻe a pau ma lalo iho.
- inā ʻo ka mea ʻole-null mua o kekahi lālani ma ke kolamu me ka helu ordinal j, a ʻo ka lālani aʻe ʻaʻole ia he null, a laila, ʻo ka mea ʻole-null mua o ka lālani aʻe e pono i loko o ke kolamu me ka helu ʻoi aʻe j.
