Polynomials¶
Basics¶
| poly1d | A one-dimensional polynomial class. |
| polyval (p, x) | Evaluate a polynomial at specific values. |
| poly (seq_of_zeros) | Return polynomial coefficients given a 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) | Returns sum of two polynomials. |
| polydiv (u, v) | Returns the quotient and remainder of polynomial division. |
| polymul (a1, a2) | Returns product of two polynomials represented as sequences. |
| polysub (a1, a2) | Returns difference from subtraction of two polynomials input as sequences. |
Warnings¶
| RankWarning | Issued by polyfit when Vandermonde matrix is rank deficient. |
