使用 PCA 的人脸识别方法

这是一个Matlab开发的数字波束形成源代码，仿真正确(This is a developed Matlab source code for digital beamforming, simulation correctly)

给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列 另外该函数用cos(x)项傅里叶级数展开一个多项式( ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04 Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with highest power on the left, expand f(x) as a sum of scalar multiples of Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)

The Wavelet Neural Network This is simple example for using of modified Morlet neural network. Levenberg-Marquardt with numerical Jacobian calculation implemented. Easy to use with other optimization algorithem e.g GA,PSO, etc. The function "xox_lm" may be useful for other optimization problem easily. The function "xox_jacobian" may be useful for Jacobian calculation easily. The function "NN_fcn" may be used by the evolutionary based neural network. The activation function "modified Morlet" will be replaceable by others.

利用函式做種子變數,用種子跑數值,計算其座落區間,最後利用matlab畫出exponential distribution(Function for seed variables, run with seed value, to calculate the located range, the last use of matlab to draw the exponential distribution.)

利用MATLAB 仿真工具设计出一个QPSK仿真程序，以衡量QPSK在理想信道、高斯白噪声信道和先通过瑞利衰落信道再通过高斯信道三种方式的调制解调得到的功率谱密度、噪声曲线、星座图及误码性能,并对仿真结果进行了分析。(QPSK simulation design and Realization Based on MATLAB)
