最速梯度法工具箱，添加方法在命令窗口中敲入pathtool，会出现一个setpath的窗口，点add folder或者add with subfolders按钮，选中你的工具箱。保存既可。任选工具箱中的一个命令，然后help一下看看是否好使。(Toolbox steepest gradient method, add the method in the command window and typing pathtool, a setpath window appears, point add folder or add with subfolders button, select your toolbox. Save both. Choose a command in the toolbox, and then help look to see if so.)

MATLAB实现ASK调制解调。 内含主文件、demo文件，高斯噪声文件等等。(MATLAB ASK modulation and demodulation.)

说明：  两种不同的假设： H1 ： 0 xn A fn wn ( ) cos(2 ) ( ) = ++ π θ n=1,2,…,N，f0 为规一化频率 H0 ： xn wn () () = n=1,2,…,N 其中 w[n]是均值为 0，方差为 2 σ n 的高斯白噪声，A 已知，样本间相互 独立，信号与噪声相互独立; 相位θ 是随机变量，它服从均匀分布 1 0 2 ( ) 20 p θ π θ π ?? ≤ ≤ = ??? 其它 1）改变输入信噪比（改变 A 或噪声方差均可），给定虚警概率，画出 输入信噪比与检测概率之间的理论曲线。(注意：理论检测曲线与样本 数有关) 2）改变样本数，用 Monte-Carlo 实验方法得出 PF＝0.001 时输入信噪比 与检测概率之间关系曲线（至少三条），并得出结论。 3）改变 M-C 实验次数，样本数不变，用 Monte-Carlo 实验方法得出 PF ＝0.001 时输入信噪比与检测概率之间关系曲线（至少三条），并得出 结论(Draw the theoretical curve between input SNR and detection probability)

hotelling transformation has been written with help of Matlab 2007a. This technology has been applied to transform images. A test image has been included in the file for explanation. It accpets 256 color map bmp image as input and produces the output.
