《数字信号处理——理论、算法与实现》胡广书 书配光盘程序 本光盘共包含三个子目录，分别是DSP_FORTRAN, DSP_C和DSP_MATLAB。DSP_FORTRAN和DSP_C各含有约40个信号处理的子程序，概括了书中所涉及到的绝大部分算法。程序分别由FORTRAN语言和C语言编写（MA模型、ARMA模型及最小方差谱估计三个算法只给出了用C语言编写的程序, 没有给出相应的FORTRAN子程序），并在PC机上调试通过。编译环境是FORTRAN77 V5. 10和TURBO C2. 0。DSP_MATLAB含有近100个用MATLAB编写的信号处理程序，它们是本书各个章节的大部分例题，使用的是MATLAB6.1。(" Digital Signal Processing- Theory, Algorithm and Implementation" Hu Guang book written with the CD-ROM CD-ROM program includes three subdirectories, namely DSP_FORTRAN, DSP_C and DSP_MATLAB. DSP_FORTRAN and DSP_C contains about 40 of the signal processing routine, the book summarizes most of the algorithms involved. Program language and C respectively written in FORTRAN (MA models, ARMA model and minimum variance spectrum estimation is given by the three algorithms only programs written in C language, did not give the corresponding FORTRAN subroutines), and in the PC, through debugging . Compilation environment is FORTRAN77 V5. 10 and TURBO C2. 0. DSP_MATLAB contains nearly 100 written using MATLAB signal processing procedures, which are most of the various chapters of the book examples, using MATLAB6.1.)

一个无刷电机仿真的模型，matlab环境，可以计算电机性能（注意：仿真的时候，对计算机硬件要求可能有点高）(a model of brushless DC motor (BLDC motor))

本文先简要介绍了矩阵的积分和微分的定义；接着通过弹簧-质量块儿-阻尼器系统的例子，阐述了求解常微分方程数值解的常用方法；最后，在前两部分的基础上，总结了用MATLAB求解形如_X(t) = f(X(t); t) 矩阵微分方程数值解的方法。(In this paper, the definition of integral and differential of matrix is briefly introduced. Then the common method of solving numerical solution of ordinary differential equation is described by the example of spring mass block damper system. Finally, on the basis of the first two parts, the solution of the form of _X is summed up by MATLAB. (T) = f (X (T); t) numerical solution of matrix differential equations.)
