Design of Filters using GUI (The code provides the user friendly GUI usage in filter design)

simple function for pictire displaying and saving in matlab + preemphasis of signal(simple function for pictire displaying and saving in matlab+ preemphasis of signal)

matlab插值与拟合（命令与示例）,一维插值、二维插值、三角测量和分散数值差值(Interpolation and fitting )

A 16F84A based timer for applications that need a timer.

matlab 简单的插值方法 方法使用 可以借鉴(matlab method uses a simple interpolation methods can learn)

在matlab里面，构造三次样条插值函数s(x)来模拟一只飞鸟外形的上部，根据已知的测试数据。(In matlab inside, construct cubic spline interpolation function s (x) to simulate the shape of the upper part of a bird, according to the known test data.)

此文件实现了让语音信号通过低通，高通，带通滤波器使其变声，并且在GUI界面上绘出了个滤波器的频率响应和语音信号的频谱。(This file allows to achieve a voice signal through a low pass, high pass, band pass filter to make it change the sound, and plotted on a GUI interface and voice signal spectrum frequency response of a filter.)

Employing Maximum Mutual Information for Bayesian Classification (Decision Theory)

matlab中QPSK的simulink仿真，包括星座图以及频谱分析(The simulink matlab in QPSK simulation, including constellation and spectrum analysis)
