Lanczos algorithm for tridiagunalization of a matrix.

说明：  hallen equation :this equation is modeled as matrix equation (the voltage is equal two the current multiplied by resistance),the object is to find the current distribution.

超宽带通信的仿真源程序，应该比较好使，请试一试(Simulation of ultra-wideband communications source, should be more so, please try)

 产生长度为1000的标准正太分布的随机信号，画出时域波形及频谱；  采用u=255的非均匀PCM编码，每符号为8bit，画输入-输出关系图；  计算信号量化噪声比（SQNR）；  信道误码率为10-3；  解码，并画出u律反变换后的信号时域波形及频谱。 扩展要求：  采用均匀PCM、量化级数可变、信道误码率可变。 ( have a standard length of 1000 is too random signal distribution, draw time-domain waveform and frequency spectrum  u = 255 using the non-uniform PCM encoding, each symbol for 8bit, drawing input- output relationship diagram  calculated quantization noise signal than (SQNR)  channel bit error rate of 10-3  decoder, and law to draw u the signal after the inverse transform time-domain waveform and frequency spectrum. Expansion of the requirements:  uniform PCM, quantization level variable, a variable channel bit error rate.)

冲击理论指的是计算结构响应的风动荡。这里,结构是一个吊桥,使用连续梁的理论建模。介绍模态耦合模型，尽可能的简单计算横向,纵向和扭转响应。结构的方法是使用。是专为那些已经拥有一些知识领域的随机振动分析和对结构风荷载。(The buffeting theory [1,2] refers to the computation of the response of a structure to wind turbulence. Here, the structure is a suspension bridge, modeled using the theory of continuous beam [3]. The frequency domain approach is used. I did not introduce modal coupling to keep the model as simple as possible. The present script computes the lateral, vertical and torsional response. A multi-modes approach is used. This script is designed for those who already have some knowledge in the field of random vibration analysis and wind loading on structures. )
