Tsuas yog li ntawd, koj yuav nrhiav tau qhov kev hloov pauv ntawm txoj haujlwm li cas?

Lub luag haujlwm txhais lus / kev hloov pauv txoj cai:

  1. f (x) + b hloov cov haujlwm b mus rau sab saud.
  2. f (x) – b hloov txoj haujlwm b mus rau nqes.
  3. f (x + b) hloov cov haujlwm b mus rau sab laug.
  4. f (x – b) hloov cov haujlwm b mus rau sab xis.
  5. -f (x) qhia txog kev ua haujlwm hauv x-axis (uas yog, upside-down).

Ib tug kuj yuav nug, dab tsi ua rau matrix linear? Thaum twg thiab muaj tib qhov loj me, nws muaj peev xwm ua tau invertible, txhais tau tias muaj qhov ntawd. Nws yeej ib txwm yog li ntawd.. Kuj, a kab tawm transformation ib txwm maps kab rau kab (los yog xoom). Lub ntsiab piv txwv ntawm a kab tawm transformation yog muab los ntawm matrix kev sib npaug.

Ib yam li ntawd, nws raug nug, koj nyeem li cas matrix?

Matrix Sau ntawv hauv matrix A ntawm sab laug, peb sau a23 txhawm rau txheeb xyuas qhov nkag hauv kab thib ob thiab kab thib peb. Ib txoj hauv kev kom nco ntsoov tias cov ntawv sau no tso cov kab ua ntej thiab kab thib ob yog xav txog nws zoo li nyeem ntawv ib phau ntawv. Koj ib txwm nyeem sideways ua ntej, ib yam li koj ib txwm sau cov kab ua ntej.

Dab tsi ua rau kev hloov pauv linear?

A linear transformation yog ib txoj haujlwm los ntawm ib qhov chaw vector mus rau lwm qhov uas hwm lub hauv paus ( kab tawm ) qauv ntawm txhua qhov chaw vector. A linear transformation tseem hu ua a kab tawm tus neeg teb xov tooj lossis daim ntawv qhia. Ob qhov chaw vector yuav tsum muaj tib qhov chaw hauv qab.
