i have attached code for boundary detection, face rcognition gradient calcul ation color spaces

说明：  用于matlab用牛顿迭代法解方程，这个在数值计算中是很重要的(Matlab by Newton' s iterative method for solving equations, this in numerical calculation is very important to)

正交频分复用（OFDM）的调制与解调以及OFDM的误码率。(Orthogonal Frequency Division Multiplexing (OFDM) modulation and OFDM demodulation and bit error rate.)

分数阶傅里叶变换 Matlab仿真实现 单分量的LFM信号的检测和参数估计( Fractional Fourier Transform Matlab simulation to achieve a single-component LFM signal detection and parameter estimation)

利用差分法求解热传导方程，然后用matlab编程解差分方程(Heat conduction equation)

这个源代码是关于遗传优化算法的源代码，里面注释很清楚(This source code is on the genetic optimization algorithm source code, which is very clear comments)

稀疏恢复算法FOCUSS，详细内容，文章中有详细的编程步骤(Sparse recovery algorithm FOCUSS, details, the article detailed programming steps)

main executing reference usage: observeWaveletDecompositionBenchmark_N_levels.m The objective is to illustrate wavelet decomposition, and to describe how operations may be done in the wavelet domain before the reconstruction. The demo decouples the wavelet operations (transform, operation in wavelet domain, and reconstruction) from the plotting. A PSNR and MSE describes the possible distortion (however minimal) of the forward and inverse wavelet transform. * Caveat: The image display may be subjected to the selected target image. The objective is to provide a simple framework for the understanding of working with wavelets.
