MATLAB 实现Fibonacci法和0.618法(MATLAB realization of Fibonacci method and 0.618 France)

一种基于分块的压缩感知实验程序代码，并附有总结，实验效果很不许错(Based block of compressed sensing experimental procedure code, along with summary, the effect is not allowed to experiment wrong)

仿真信号x(n)的1又1/2维谱，给出了一个matlab实例，能够获得谱的图形(The dimensional spectrum of the simulation signal x (n) 1 1/2, gives a matlab instance, it is possible to obtain the spectrum Pattern)

这是偶近几年来研究的多种PID控制程序，有灰色PID，神经网络自适应PID，模糊PID等等，程序多多，肯定会对大家有帮助的！()

说明：  频域的模态参数识别方法之一，可以对振动信号进行分析处理，得出结构的固有频率，阻尼比，振型系数，方法很好，程序完整，(Frequency-domain modal parameter identification methods that can analyze the vibration signal processing, draw the structure of natural frequencies, damping ratio, mode shape coefficient, very good method, program integrity,)

FCCUWB，关于UWB的FCC规范的频谱图，给出了相应的说明和解释(FCCUWB, on the FCC UWB standard spectrum, the corresponding description and explanation)

说明：  递推最小二乘法的matlab程序，亲测可出图(recursive least squares)

This is the matlab code for Direct Sequence Spread Spectrum generation

自己编写的短时傅里叶变换（STFT）程序，短时傅里叶变换可以获得非平稳信号的时频图，主要原理是用滑窗截取一段信号，认为这一段时间内信号是平稳的，对其进行fft变换获得频谱(I have written a short time Fourier transform (STFT) program, short-time Fourier transform can be obtained non-stationary signal frequency diagram, the main principle is the interception of a signal with a sliding window that within this period of time the signal is stationary, access to spectrum fft transform them)

利用PRNU的图像指纹识别算法，可用于进行图像认证，来源辨别等。主要用于数字图像取证方面。(PRNU image use fingerprint recognition algorithm, can be used for image authentication, and other sources to identify. Mainly used for digital image forensics.)
