Polynomials¶
Basics¶
| poly1d(c_or_r[, r, variable]) | A one-dimensional polynomial class. |
| polyval(p, x) | Evaluate a polynomial at specific values. |
| poly(seq_of_zeros) | Find the coefficients of a polynomial with the given sequence of roots. |
| roots(p) | Return the roots of a polynomial with coefficients given in p. |
Calculus¶
| polyder(p[, m]) | Return the derivative of the specified order of a polynomial. |
| polyint(p[, m, k]) | Return an antiderivative (indefinite integral) of a polynomial. |
Arithmetic¶
| polyadd(a1, a2) | Find the sum of two polynomials. |
| polydiv(u, v) | Returns the quotient and remainder of polynomial division. |
| polymul(a1, a2) | Find the product of two polynomials. |
| polysub(a1, a2) | Difference (subtraction) of two polynomials. |
Warnings¶
| RankWarning | Issued by polyfit when the Vandermonde matrix is rank deficient. |
