Qiime sugan

Qiime sugan ((Af-Ingiriis: Absolute Value)) waa Fansaar xisaabeed waxaana lagu gartaa saddexdaan astaamood:

• Hadii ${\displaystyle ||u||}$ ay le'egtahay eber markaa ${\displaystyle u=0}$ wuxuu noqnayaa ${\displaystyle u\neq 0}$ oo ah ${\displaystyle ||u||}$ ka weyn eber
• ${\displaystyle ||\lambda u||=|\lambda |.||u||}$
• ${\displaystyle ||u_{1}+u_{2}||\leq ||u_{1}||+||u_{2}||}$

Qiimaha suga ee tira kasta waa tiro togan waxay doonto tirada markii hore ha ahaatee.

Qiimaha sugan ee xarriiqa tirada

<${\displaystyle {\frac {.....L.....-.....k}{-6.....0.....6}}\,}$> Haddaad lix tallaabo ugu socotid unugga 0 xagga midigta waxaad gaareysaa K oo kulankeedu yahay 6, marka waa inaad ogaataa fogaanta L iyo unuggu isu jiraan in ay lamid tahay fogaanta K iyo unuggu isu jiraan. Haddaba qiimaga suga ee -6 iyo +6 waa fogaanta L iyo 0 isu jiraan iyo fogaanta K iyo 0 isu jiraan; waana 6.

Asatada u go'an qiimaha sugan waa laba xarriiqood oo qotama oo labada hareerood laga mariyo tirada qiimaheeda suagan la doonayo.

Marka fogaan L iyo 0 isu jiraan

= | -6 | = 6

Fogaanta K iyo 0 isu jiraa

= | +6 | = 6
