matlab处理信号处理的程序，简单但很有参考价值(matlab procedures to deal with signal processing, simple but useful reference)

this code derivats image and get derivated image to you

数学建模清华数模讲义\model10b (Mathematical modeling Qinghua digital-analog handouts model10b)

说明：  论文的仿真代码，中文字数必须大于20个字。。。。(optimal simulation, but not include CVX function,just take the result after optimal computing)

Spherical harmonic wavelets or Legendre wavelets are compactly supported wavelets, which are derived from Legendre polynomials. These wavelets are suitable for problems of spherical symmetry since they correspond to the colatitudinal part of "spherical harmonics" in spherical polar coordinates. reference URL

The PAPR of QAM system is plotted against Complementary cumulative distribution function

说明：  ofdm的时域仿真代码，matlab下正常。(ofdm s time domain simulation code with matlab,it s works well.)

说明：  用matlab编的小程序，希望对大家有所帮助！(using Matlab series of small programs, we hope to help!)

数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which part of the program were modified)
