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. |
Fitting
| polyfit (x, y, deg[, rcond, full]) |
Least squares polynomial fit. |
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. |
