QRS-detection-by-Caceres

通过卫星的测量方程和状态方程来求解卫星的姿态。包括四元数，角度，角速度等等。(By satellite measurements to solve equations and state equations of satellite attitude. Including the quaternion, angle, angular velocity and so on.)

matlab的仿真追击程序模拟，欢迎数学建模的朋友下载。(matlab simulation program to simulate pursuit, welcome friends from mathematical modeling to download.)

国外的一个用C实现的类似matlab数学库，功能貌似很强大，很多功能已经有源码了，喜欢C语言的人有福了。(Foreign matlab math library in C, the function looks like a very powerful, many functions have been source of the Blessed are those who like the C language.)

基于多线程机制的，利用Matlab编写，粒子群优化算法。目标变量采用归一化处理，适用于所有的优化函数。优化函数自定义为fitness(x)。(Based on multi-threading mechanism, the use of Matlab to prepare, particle swarm optimization algorithm. Target variables using normalized treatment applies to all of the optimization function. Since the optimization function is defined as fitness (x).)

说明：  学习Matlab的经典入门教程,希望对学习M的人有所帮助(Matlab Tutorial classic study, people who want to help to learn M)

对GRNN的进行改进，用来做预测，其中对于每一组输入向量给其一个平滑因子，预测的效果不错(Improvements on the conduct of GRNN, used for prediction, in which each set of input vectors for a smoothing factor to its forecast good results)

说明：  PID控制器的优化问题就是确定一组合适的参数Ki,,Kd,Ka，使得指标达到最优。常用的误差性能指标包括ISE、IAE、ITAE、ISTE等。(The optimization problem of PID controller is to determine a set of suitable parameters Ki, KD, Ka, so as to achieve the optimal index. The commonly used error performance indexes include ise, IAE, ITAE, ISTE, etc.)

使用MATLAB对DSB-AM进行仿真：双边带幅度调制的过程以及对其中所包含的对信号的频谱分析都可以通过MATLAB中的M语句及相关函数来实现。假如信号m(t)=cos(m)以dsb-am方式调制载波c(t)=cos(20*pi*t),所的信号为y(t)，并将采样频率定为 fs=100Hz,则可在MATLAB中设计程序对该幅度调制的结果进行仿真，绘制已调信号波形和频谱分析。(It is a example for DSB-AM based on MATLAB .)

BPSK在AWGN信道下的仿真程序，matlab代码(BPSK in AWGN channel under the simulation program)

power_transformer,matlab仿真文件,电力电子、功率电子控制方面很有价值，调试通过(aspects of power_transformer, matlab simulation files, power electronics, power electronics control valuable debugging through)
