solving heat problem by FEM

时频分析，用于信号的时频分析，短时傅里叶变换、小波、脊线提取、一些信号的生成，等等。(Time-frequency analysis, time-frequency analysis for signal, short time Fourier transform, wavelet ridge line extraction, generate some signal, and so on.)

3阶iir滤波器设计，不采用matlab自带的滤波子程序，完全自己编写程序，可以十分方便的转化为c语言。(3-order IIR filter design, do not use built-in filtering matlab Subroutine entirely their own programming, can be transformed into a convenient c language.)

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

State Space/ Kalman Filter Toolbox,Author: Marcelo Perlin / (PhD Student) / ICMA – Reading University,This toolbox was designed to simulate and fit linear state space models with the kalman filter approach. The main literature I used for this particular package is Kim and Nelson (1999) and Hamilton (1994).

用MATLAB语言编写的源码可产生正弦波表，这个就是是数字信号获得正选值的方法 (Sine table MATLAB program)
