En matris \u00e4r en rektangul\u00e4r matris av tal, symboler eller uttryck ordnade i rader och kolumner. Detta rektangul\u00e4ra rutn\u00e4t av siffror anv\u00e4nds ofta inom matematik, elektroteknik och datavetenskap. Matriser skapades ursprungligen f\u00f6r att beskriva systemet med linj\u00e4ra ekvationer.<\/p>\n

Nu anv\u00e4nds matriser i stor utstr\u00e4ckning inom bildbehandling, genetisk analys, big data och programmering. Addering och subtraktion av matriser \u00e4r de tv\u00e5 vanligaste matrisoperationerna. I den h\u00e4r artikeln f\u00e5r du l\u00e4ra dig hur du adderar och subtraherar tv\u00e5 matriser.<\/p>\n

F\u00f6lj dessa regler f\u00f6r att l\u00e4gga till tv\u00e5 matriser:<\/p>\n

Tv\u00e5 matriser kan bara l\u00e4ggas till om de \u00e4r av samma ordning. Om de tv\u00e5 matriserna \u00e4r av samma ordning, l\u00e4gg till motsvarande element i de tv\u00e5 matriserna, dvs l\u00e4gg till de element som har samma positioner. <\/p>\n

\n<\/figure>\n

I exempel 1 kan matriserna l\u00e4ggas till eftersom de har samma ordning. I exempel 2 kan matriserna inte l\u00e4ggas till eftersom de inte har samma ordning.<\/p>\n
