Nws txhais tau tias koj nqa a matrix , cia nws ua rau vector, thiab nws rov qab vector nrog tus lej scalar pem hauv ntej.

Ntxiv mus, lub cim lambda txhais li cas hauv lej?

Lambda yog feem ntau siv raws li cov cim rau wavelength hauv science thiab engineering. Lambda calculus (tseem sau ua λ-calculus) yog ib tug formal system nyob rau hauv lej logic rau kev nthuav qhia xam raws li kev ua haujlwm abstraction thiab daim ntawv thov siv kev sib txawv ntawm kev khi thiab hloov pauv.

Tsis tas li ntawd, qhov eigenvalue ntawm matrix yog dab tsi? Eigenvalue . Eigenvalues yog ib txheej tshwj xeeb ntawm scalar txuam nrog ib txoj kab ke ntawm kab zauv (piv txwv li, a matrix equation) uas tej zaum kuj hu ua tej yam hauv paus ntsiab lus, yam ntxwv qhov tseem ceeb (Hoffman thiab Kunze 1971), muaj nuj nqis tsim nyog, los yog latent keeb kwm (Marcus and Minc 1988, p. 144).

Ua raws li qhov pom, lambda hauv Matrix yog dab tsi?

Lambda matrix . A matrix nws cov ntsiab lus yog polynomials hauv qhov sib txawv λ. Cia F[λ] ua ib lub npe polynomial uas muaj cov txheej txheem ntawm tag nrho cov polynomials nyob rau hauv λ nrog coefficients nyob rau hauv F. A non-zero mxn matrix tshaj F[λ] yog hu ua λ- matrix.

Lambda formula yog dab tsi?

Wavelength yog sawv cev nrog tsab ntawv Greek lambda : hli. Nws yog sib npaug rau qhov nrawm ntawm nthwv dej, muab faib los ntawm qhov zaus. Wavelength yog qhia nyob rau hauv units ntawm meters (m). λ = wavelength, qhov kev ncua deb ntawm nthwv dej crests (m) v = nthwv dej tshaj tawm, qhov ceev uas nthwv dej txav mus rau hauv ib qho kev taw qhia (m / s)
