Poly1d¶
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. |
