computation of ybus in ieee 39 bus

用HOUGH检测直线的时候是两个未知量,因为轴半径和相角可以确定一条直 线，在HOUGH域出现累计最大点就可能是原域中的直线。现在回到圆的检测 上来，确定一个圆需要什么：X坐标，Y坐标，半径三个未知量吧，好了，现在， 你做一个三维空间的HOUGH域，以这三个未知量作为三个轴，现在按照一定步长 进行三重循环，在最内层循环是这样的，X,Y 确定，以不同的半径进行搜索，如 果你的X,Y刚好就是实际图像的X,Y处，半径又搜索到实际真实的半径(The HOUGH detect straight when two unknown amount of axis radius and phase angle can be determined in a straight line, in the HOUGH domain cumulative maximum point may be the straight line of the original domain. Now back to the circle detection up to determine what a circle: X coordinate, Y coordinate, radius three unknowns, now, you do the HOUGH domain of a three-dimensional space, three to three unknown quantity as axis, in accordance with a certain step size triple loop, is such that in the innermost loop, X, and Y determined search for a different radius, If you X, Y, exactly is the actual image of the X, Y, at the radius radius of the search to the actual real)

数字调制信号与仿真的书本中的第四章节的MATLAB仿真代码，需要的话可以跟我联系取得其他章节的代码(And simulation of digital modulation signals in the fourth chapter of the book MATLAB simulation code, you need to contact me if you can obtain the other chapters of the code)

大斜视角下，点目标的距离多普勒算法(RDA,Range_Doppler Algorithm)仿真，Matlab语言。(Range_Doppler Algorithm,Matlab)

说明：  灰度图像的位面图程序 matlab环境下写的 希望能有帮助(Gray image Bit plane map program， hopes to help you)

说明：  matlab处理音频信号显示音频信号的频谱图，然后滤波，并对滤波前后音频信号的频谱图进行对比，接着对原始音频信号的频谱去掉若干个点与远视音频信号的频谱比较，最后对音频信号的频谱及相位进行三维显示(audio signal processing matlab)

文件主要是对利用压缩感知对MRI进行数据重构，重构方式是基于全变分共轭梯度法(the folder contains some Matlab codes used for applying compressed sensing(CS) in MRI. morever, these codes are based on BP-TV.)
