世界上最好的微积分教材，搞程序的，研究的，数学的都应该了解，这个是James.Stewart的Calculus第七版，英文原版，彩色的，值得珍藏。(The world' s best calculus textbook, engage in programs, research, mathematics should understand that this is James.Stewart seventh edition of Calculus, English original, colorful and worth treasuring.)

数值分析中运用matlab用hermit插值多项式逼近函数(Numerical analysis using matlab function hermit interpolation polynomial approximation)

用于模拟混凝土单元的弹塑性模型，并有损伤变量，在ABAQUS中umat中输入弹性模量，泊松比与屈服应力即可。(The elastic-plastic model for the simulation of concrete unit, and the damage variable in the ABAQUS umat enter the elastic modulus, Poisson' s ratio and yield stress can be.)

快拍数不同时，DMI直接矩阵求逆算法进行波束形成的(The snapshot number is not the same, DMI direct matrix inversion algorithm beamforming)

说明：  实现粒子滤波。包含运行模型，测量模型，重采样和归一化(Implement particle filter. Including operation model, measurement model, resampling and normalization)

预处理CG算法，在进行共轭梯度法之前先对系数矩阵进行预处理，再进行迭代(pretreatment congruent gradient)

两种SQR迭代法:将x^K与上次计算的结果做加权平均作为最后结果(Two kinds SQR iterative method:the x ^ K and the results of the last calculated as a weighted average of the final results do)

基于最小二乘估计的圆心拟合，可计算出圆心坐标及半径(Estimates based on least squares fitting of the center of a circle, calculate the center coordinates and radius)

运用格子Boltzmann方法中的伪势模型，模拟胀大平面流道中的两相流动，左边幂律流，右边牛顿流体。得出流动过程中，各个瞬态的结果。(Using lattice Boltzmann method of pseudo potential model to simulate the swell plane channel flow, on the left side of the power-law fluid flow. On the right side of the Newtonian fluid. In the process of flowing, the result of each transient.)

说明：  cuda矩阵乘法 通过GPU并行运算实现乘法的加速(cuda GPU parallel matrix multiplication operation by the accelerated realization of multiplication)
