Allocates a new Chebyshev object with $size sample points. gsl_cheb_free ($cheb) Deallocates memory associated to $cheb. Returns void. gsl_cheb_init ($cheb,$function, $lower, $upper) gsl_cheb_init ($cheb, sub { sin(cos($_[0])) }, 0, 10 ); Initiate a Chebyshev object with a function and upper and lower bounds. Returns void.

In order to work efficiently the algorithm requires a precomputed table of Chebyshev moments. type gsl_integration_qaws_table ¶ This structure contains precomputed quantities for the QAWS algorithm. gsl_integration_qaws_table *gsl_integration_qaws_table_alloc(double alpha, double beta, int mu, int nu) ¶

Chebyshev Approximation 车比雪夫逼近 gsl_chebyshev.h 提 供了 [-1, 1] 上一组正交多项式，这对应的是 1/sqrt (1-x^2) 为权的函数空间。 首先用 gsl_cheb_alloc () 分配空间产生 gsl_cheb_series 结构，然后 gsl_cheb_init ()，最后 gsl_cheb_free ()。 提供了计算函数值、函数值误差，导函数和积分。 Series Acceleration 级数加速 gsl_sum.h 提 供了一个 Levin u-transform 的东西，没听说 …

gsl_integration_fixed_type * gsl_integration_fixed_chebyshev ¶ This specifies Chebyshev type 1 quadrature integration. The parameters alpha and beta are ignored for this type. gsl_integration_fixed_type * gsl_integration_fixed_gegenbauer ¶ This specifies Gegenbauer quadrature integration. The parameter beta is ignored for this type.
