esprit算法，基于均匀线阵的阵列信号处理波达方向的matlab程序。(this is a malab about esprit.)

对信号进行短时傅里叶变换的逆变换，通过调用该函数查看信号进行处理后的时域信息(this code is used to processing the istft, and anslysis the distribution of the signal with time )

快速傅里叶变换和小波包能量提取代码，可以对采集到的信号进行预处理。(Fast Fourier transform and wavelet packet energy code, can be collected signal preprocessing.)

matlab高通滤波器，可以直接在matlab上运行，显示(matlab high-pass filter can be run directly in matlab to show)

dft and idft with and with out function

pso code, a very good code using matlab

PSO算法和最速下降法混合算法，求解单目标优化问题，测试函数是非线性方程组，解决MinF(x)的问题。(PSO algorithm and steepest descent method hybrid algorithm for solving single-objective optimization problem, the test function is non-linear equations, solving MinF (x) of the problem.)

获得图像局部增强时，每个象素的指数增强系数，指数增强系数有原图像中的灰度值与其周边象素比较获得([Coeff_en_local, lum_mask]=enhance_coeff_local_bilateral(lum_ori,window_r,sigmad,sigmar))
