matlab boost PID 调节电路，已经调好(matlab boost pid )

用MATLAB来实现计算器，功能全面，请大家指正(Realization Calculator)

认知无线电网络，频谱管理，频谱分配算法研究(Spectrum allocation)

说明：   本程序可以绘制p3曲线，直接输入cv、cs、EX,也通过降雨或径流数据计算绘制 [cs,cv,ma] = p3plot(a,kk,b,bb,y1,cs_cv,ma,cs,cv,x0) a=20 横向网格条数 kk=200 纵坐标标注间隔（间隔要是最大值和最小值差的整数倍） b=2000 纵坐标最大值 bb=0 纵坐标最小值 y1=[] 降雨量，横向矩阵输入,如果没有请输入[] cs_cv=[2] 没有，请输入[] ma=[] 年平均降雨量，没有输入[] cs=[] 没有，请输入[] cv=[] 没有，请输入[] x0=0.01 初始概率点，百分数,没有输入[]( this program can draw P3 curve, direct input CV, CS, EX, also by rainfall or runoff data calculation and drawing The [cs, CV, ma] = p3plot (a, KK, B, BB, Y1, cs_cv, Ma, CS, CV, x0) The a=20 of the number of horizontal grid The kk=200 longitudinal coordinate labeling interval (interval if the maximum value and the minimum value of the integer times the difference) The b=2000 of the maximum longitudinal coordinates The bb=0 of the minimum longitudinal coordinates The y1=[] rainfall, transverse matrix input, if not please input [] The cs_cv=[2] no, please enter [] The ma=[] of the average annual rainfall no input [].

CAPM代码，资本资产定价模型在Matlab中的实际应用。(Capital Asset Pricing Model with Missing Data)

说明：  在simulink中先完成车辆状态的仿真计算，再用卡尔曼滤波估算车辆质量。(In Simulink, the simulation calculation of vehicle state is completed first, and the vehicle mass is estimated by Kalman filter.)

KMV模型用来估计借款企业违约概率的方法。该模型认为，贷款的信用风险是在给定负债的情况下由债务人的资产市场价值决定的。该模型了债务人的债权和股权的市场公允价值.(KMV model is used to estimate the probability of default of the borrower methods. The model considers the credit risk of loans given in the case of liability is determined by the market value of the debtor s assets. The model of the fair value of the debtor s debt and equity markets.)

卫星通信信道链路参数计算与模拟.由于降雨对不同频段下的卫星通信造成不同的衰减，通过计算与模拟卫星通信信 道链路参数，可以设计出可靠性更高的卫星通信系统。(Satellite communication channel link parameter calculation and simulation. Due rainfall in different frequency bands for satellite communications under different attenuation caused by calculation and simulation of satellite communication channel link parameters, you can design a higher reliability of satellite communications systems.)
