ABAQUS-UMAT

利用labiew主程序实现单片机与主机的串口通信，实现温度的采集，然后通过比例积分算法的控制，输出一定占空比的波形驱动电机，实现恒温水箱的控制系统(MCU and host serial communication labiew main program, to achieve the acquisition of temperature, and then through the control of the proportional integral algorithm, the output of a certain duty cycle waveform drive motor, constant temperature water tank control system)

说明：  共轭梯度法求解线性方程组,主要采用FR共轭梯度法(solve liner solutions from CG)

基于干扰矩阵的重置和导向矢量估计的数字波束形成，程序经过优化，可运行，里面包含了一个矩阵求积分的子程序，可参考(Reset based on interference matrix and steering vector estimation of digital beamforming, the program has been optimized to run, which contains a matrix integral subroutines, refer to)

王勖成的《有限单元法》资料包，包括pdf书籍、课后习题答案以及有限元分析教学程序FEATP源码！(The package of finite element method by Wang Xucheng, including pdf books, after-school exercise answers and finite element analysis the teaching programFEATP source!)

用牛顿迭代法估计正弦信号的幅度，相位，频率，选用多次montecalor算法估计参数均值，并与理论上参数估计的CRLB下限进行比较。(Newton iterative method estimates the sinusoidal signal amplitude, phase, frequency, use multiple montecalor algorithm to estimate the parameters mean, and with the theoretical limit of parameter estimation CRLB compare.)

这是用于将格点数据转化站点数据的fortran程序，比较详细，可以画图(This is a fortran program for the grid data into the site data in more detail, you can draw)

西安电子科技大学葛德彪教授书后所附fortran程序(Xidian University, Professor Ge Debiao book accompanying fortran program)

铁木辛柯梁梁单元有限元程序，可以自动形成刚度阵，质量矩阵(Ironwood oct Ke Liangliang unit finite element program can automatically form stiffness matrix, mass matrix)

关于simple算法，希望站长能够让小弟加入这个学习的行列。(on simple algorithms, hoping to let the younger station to join the ranks of the study.)
