matriz

1. Anat.
sin. útero

Obulu ernaldua jasotzen duen eta kanporatu bitartean fetua gordetzen duen ugaltze-organoa, pareta muskulutsuak dituena.

2. Geol.

Fosilen bat, pikorren bat, kristalen bat edo beste partikularen bat barnean duen tamaina finagoko materiala.

3. Mat.

Errenkadatan (lerro horizontaletan) eta zutabetan (lerro bertikaletan) antolaturiko elementuek osatzen duten taula angeluzuzena. (aij) ikurraz adierazten da, i errenkadaren zenbakia eta j zutabearen zenbakia izanik. Matrizearen ordena (edo matrizearen dimentsioa) m × n moduan adierazten da, m errenkada-kopurua eta n zutabe-kopurua izanik. Matrizeak batu eta biderkatu egin daitezke, baldintza batzuen mende, baita eskalar batez biderkatu ere. Matrizeak aljebra linealean erabiltzen dira. Determinanteak ez bezala, matrizeak ez du zenbakizko baliorik, baina matrizeak elementuen arteko erlazioei buruzko arazoak aztertzeko erabiltzen dira.

4. Teknol.
sin. estampa, troquel

Forjaketa mekanikoan metala konprimatzeko erabiltzen den moldea eta bi molde-erdietako bakoitza.

5. Teknol. Mek.
sin. estampa, troquel

Ebaketa bidezko eta deformazio bidezko konformazioetan erabiltzen den erreminta-bikotea osatzen duten erremintetako bat, bietan handiena eta bere barnean bestea (puntzoia) hartzen duena. Bi erremintak elkartzean, tartean den objektuari forma jakin bat ematen diote. Forma emateko ez baizik eta ebakitzeko erabiltzekoa denean, forma jakin bateko ertz ebakitzaileak ditu, eta, presioz, forma horretako piezak (larrua, kartoia, txapa, etab.) ebakitzen ditu.

3. Mat.
Errenkadatan (lerro horizontaletan) eta zutabetan (lerro bertikaletan) antolaturiko elementuek osatzen duten taula angeluzuzena. (aij) ikurraz adierazten da, i errenkadaren zenbakia eta j zutabearen zenbakia izanik. Matrizearen ordena (edo matrizearen dimentsioa) m × n moduan adierazten da, m errenkada-kopurua eta n zutabe-kopurua izanik. Matrizeak batu eta biderkatu egin daitezke, baldintza batzuen mende, baita eskalar batez biderkatu ere. Matrizeak aljebra linealean erabiltzen dira.
