FBP投影算法 用来实现CT图像的复原 调试通过 希望对初学者有用(FBP algorithm for the reconstruction of CT image)

四种IIR滤波器的设计与性能对比（巴特沃斯，切比雪夫I、II型，椭圆滤波器）(The four IIR filter design and performance comparison (Butterworth, cut Chebyshev I, type II, elliptic filter))

说明：  基本的遗传算法实现，并举了一个简单的例子，编程语言matlab(Basic genetic algorithm, both a simple example, programming language matlab)

说明：  我用过的一些kalman程序，希望对大家有帮助，对于初学者来说，或许有点启发。(FFT)

遗传算法的matlab实现代码，已验证无错误(Genetic algorithm matlab code, verified error)

本文档用于《统计建模与R软件》第六章至第九章课后答案。(This document is for the " Statistical modeling and R software" Chapter VI to Chapter IX after the answer.)

用MATLAB作切比雪夫-1型低通滤波器设计(Using MATLAB for-1 Chebyshev-type low-pass filter design)

CT图像重建 ART算法 利用代数重建算法对CT投影图像进行重建(ART algorithm for CT image reconstruction using algebraic reconstruction of CT projection image reconstruction)

Three matlab-based tools have been developed for the convenient assess- ment of stability conditions for linear and nonlinear systems. The fi rst is a more helpful and defi nitive version of nyquist, which has features of automatic zooming and which displays on the real axis a numeral (‘0’, ‘1’ etc.)

本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。(This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.)
