class numpy.polynomial.chebyshev.Chebyshev(coef, domain=None, window=None)[source] -
A Chebyshev series class.
The Chebyshev class provides the standard Python numerical methods ?+?, ?-?, ?*?, ?//?, ?%?, ?divmod?, ?**?, and ?()? as well as the methods listed below.
Parameters: coef : array_like
Chebyshev coefficients in order of increasing degree, i.e.,
(1, 2, 3)gives1*T_0(x) + 2*T_1(x) + 3*T_2(x).domain : (2,) array_like, optional
Domain to use. The interval
[domain[0], domain[1]]is mapped to the interval[window[0], window[1]]by shifting and scaling. The default value is [-1, 1].window : (2,) array_like, optional
Window, see
domainfor its use. The default value is [-1, 1].New in version 1.6.0.
Methods
__call__(arg)basis(deg[, domain, window])Series basis polynomial of degree deg.cast(series[, domain, window])Convert series to series of this class. convert([domain, kind, window])Convert series to a different kind and/or domain and/or window. copy()Return a copy. cutdeg(deg)Truncate series to the given degree. degree()The degree of the series. deriv([m])Differentiate. fit(x, y, deg[, domain, rcond, full, w, window])Least squares fit to data. fromroots(roots[, domain, window])Return series instance that has the specified roots. has_samecoef(other)Check if coefficients match. has_samedomain(other)Check if domains match. has_sametype(other)Check if types match. has_samewindow(other)Check if windows match. identity([domain, window])Identity function. integ([m, k, lbnd])Integrate. linspace([n, domain])Return x, y values at equally spaced points in domain. mapparms()Return the mapping parameters. roots()Return the roots of the series polynomial. trim([tol])Remove trailing coefficients truncate(size)Truncate series to length size.
