Matlab连续系统的数字PID控制程序，可实现A/D，D/A功能，符合现场实际情况。(Matlab figure for PID control system procedures, can be A/D, D/A functions, in line with the actual situation at the scene.)

自己编写的 matlab gui 可以实现任意多边形定点参数输入 然后使用Sutherland_Hodgeman等算法进行多边形被矩形截取的演示程序(I have written matlab gui can realize arbitrary polygon fixed parameters such as input and then use the algorithm Sutherland_Hodgeman rectangular polygon was the interception of the demo program)

给文件重命名，以0001为开始，前面的0个数自动确定,按照文件夹中文件的总个数。(To rename the file to 0001 for the start, the number of zeros is automatically determined according to the total files in the folder number.)

采用LCL滤波器的并网逆变器双闭环控制系统仿真,系统采用电感电流外环电容电流内环(The double closed-loop control system of grid-connected inverter with LCL filter is simulated. The system adopts inductance current outer loop and capacitance current inner loop.)

matlab编写的用霍夫曼变换检测圆的算法 对初学者有帮助(Function uses Standard Hough Transform to detect circles in a binary image. According to the Hough Transform for circles, each pixel in image spac corresponds to a circle in Hough space and vise versa. upper left corner of image is the origin of coordinate system.)

粒子群算法的一些程序 标准PSO算法 范例 (PSO Matlab progam)

FDM modulation with matlab

Tutorial Two (You should run it in the Command Window)

多相合成：将多个窄带信号合称为一路宽带信号，合成后的信号频率无相互干扰(The multi-phase synthesis: multiple narrowband signals collectively known as the way broadband signals, the synthesized signal frequency interfere with each other)

说明：  对于已定义的包含从0到15的整数的列向量xsym，就可以利用modem.qammod对象的modulate方法来调制它。其中M值为16，亦即为码字表的大小。 对已调制信号可采用awgn函数添加加性高斯噪声。其中比特能量与噪声功率谱密度的比值，Eb/N0，设置为10dB。 (The method comprising modulate integer from column vectors xsym 0 through 15, can use the defined object modem.qammod modulating it. Wherein M is 16, i.e., a codeword size of the table. Modulated signal can be used for awgn function to add the additive Gaussian noise. Wherein the ratio of bit energy to noise power spectral density, Eb/N0, is set to 10dB.)
