这不是一个标准MATLAB的函数 H = hpfilter （类型，男，氮， D0 ， n ）的创建传递函数的高通滤波器，氢，指定的类型和大小MxN 。可能的值类型， D0和N是： 理想 理想高通滤波器的截止频率D0 。 Ifsupplied ， n是被忽略。 btw 巴特沃思高通滤波器 n阶和截止D0 。 gaussn 高斯高通滤波器的截止（标准偏差） D0 。 如果提供，正被忽略。 M和N应该是偶数的密度泛函过滤。(THIS IS NOT A STANDARD MATLAB FUNCTION H = hpfilter (type,M,N,D0,n) creates the transfer function of a highpass filter, H, of the specified type and size MxN. Possible values for type, D0, and n are: ideal Ideal highpass filter with cutoff frequency D0. Ifsupplied, n is ignored. btw Butterworth highpass filter of order n, and cutoff D0. gaussn Gaussian highpass filter with cutoff (standard deviation)D0. )

教授 Andrew Ng 的maching learning 课excise1答案(the answer of the maching learning teaching by Andrew Ng )

说明：  用C++实现了最小二乘法，和matlab的同名函数功能 相同(Code to dispaly how to implement lsqlin function in C++)

利用matlab将输入的rgb图像转化为灰度图像后，利用阈值求的二值图像，边缘算子求的边缘图像，边缘图像求归一化不变矩，Hu矩。(Matlab input rgb image to grayscale image, using the binary image threshold seeking child seeking the edge of the image, the edge operator, the edge of the image seeking normalized invariant moments, Hu moments.)

上课的时候老师让我们小组做的一个载波相位与位定时联合估计的matlab仿真实现的程序，很强大的哦！呵呵，希望可以帮助到大家！(Joint estimation algorithm)

本文算法是将24 位真彩图的亮度分量分块 DCT ,然后利用DCT 量化系数的奇偶特性嵌入8 位灰度水印图,并通过PN 序列加密来保证水印的 安全性。算法中,将灰度图像转换为二进制数据 流,置乱后扩频调制,隐藏在宿主DCT 系数量化值 中,提取时不需要宿主信号,实现水印信号的盲提 取。(This algorithm is 24-bit true color pictures of the luminance component of block DCT, quantization DCT coefficients and then use the parity properties of 8-bit grayscale watermark embedding map, and through the PN sequence of encryption to ensure the security of the watermark. Algorithm, the gray image into binary data stream, scrambling after the spread spectrum modulation, hidden in the host DCT coefficient quantization values, the extraction does not require the host signal, the blind watermark extraction.)

此模型为双向DCDC，可用于电池充放电，燃料电池升降压模拟等。采用PWM控制IGBT管占空比。可直接运行，在其基础上修改简单(This model is a bidirectional DCDC, which can be used for battery charging and discharging, fuel cell buck-boost simulation. PWM control of the IGBT tube duty cycle. Can be run directly, modify it on the basis of simple)

This code is to simulate 16-PSK and 16-QAM over AWGN channel
