Kev piav qhia. C=coeff(Mp) returns in a big matrix C the coefficients of the polynomial matrix polynomial matrix Nyob rau hauv lej, ib tug polynomial matrix los yog matrix ntawm polynomials yog a matrix uas nws cov ntsiab lus yog univariate los yog multivariate polynomials Sib npaug, ib tug polynomial matrix yog ib tug polynomial uas nws coefficients yog matrices. https://en.wikipedia.org › wiki › Polynomial_matrix
Polynomial matrix - Wikipedia
Mp. C yog muab faib ua C=[C0, C1, …, Ck] qhov twg Ci tau teem rau hauv kev nce qib k=max(degree(Mp)) C=coeff(Mp, v) rov qab cov matrix ntawm coefficients nrog degree hauv v.
%z hauv Scilab yog dab tsi?
%z yog the polynomial hauv cov xwm txheej nyuaj los ntawm default, z=poly(0, "z"). Qhov kev sib txawv no yog siv los tsim cov polynomials.
poly muaj nuj nqi hauv Scilab yog dab tsi?
Scilab los nrog lub luag haujlwm tsim los txhais cov npe. Scilab muaj nuj nqi rau kev txhais lus ntau yog poly. Nyob ntawm cov kev xaiv ntawm kev ua haujlwm, cov polynomial tuaj yeem txhais raws li nws cov coefficients lossis nws cov hauv paus.
Koj siv poly hauv Scilab li cas?
Yog v yog vector,
- poly(v, "x", ["roots"]) yog cov polynomial nrog cov hauv paus ntsiab lus ntawm v thiab "x" raws li kev sib txawv. (Hauv qhov no, cov hauv paus hniav thiab poly yog qhov ua haujlwm rov qab). …
- poly(v, "x", "coeff") tsim cov polynomial nrog cim "x" thiab nrog coefficients nkag ntawm v (v(1) yog lub sij hawm tas mus li ntawm polynomial).
Poly hauv polynomial yog dab tsi?
Poly txhais tau tias "ntau" hauv Greek, thiab nomial los ntawm Latin npe, lossis "lub npe." Hauv cov ntsiab lus lej, qhov no dhau los ua "ntau cov ntsiab lus." Muaj ob peb lwm txoj cai hais txog polynomials (exponents yuav tsum yog tus lej zoo, piv txwv li), thiab koj tus kws qhia lej tuaj yeem sau koj rau ntawm lawv. Cov ntsiab lus ntawm polynomial.
