代码说明：

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出.以第1边界条件为例,用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组.通过Matlab编制三次样条函数的通用程序,可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图.(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. Boundary conditions in the first example, the second derivative with node represents a cubic spline interpolation function, solving equations associated with catch-up method group. preparation of common procedures cubic spline function through Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation has been calculated and displayed for each sub-interval graphs.)

说明：经典书籍剑桥大学大学出版社：无线通信基础(Book Description: The past decade has seen many advances in physical layer wireless communication theory and their implementation in wireless systems. This textbook takes a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multi-input, multi-output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from real wireless systems such as GSM, IS-95 (CDMA), IS-856 (1 x EV-DO), Flash OFDM and UWB (ultra-wideband). Particular emphasis is placed on the interplay between concepts and their implementation in real systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interes)
