ABAQUS UMAT code 适用于平面应变，轴对称的黏弹塑性线性应变硬化材料，适用于大变形。(The ABAQUS UMAT code applies to plane strain, axisymmetric viscoelastic plasticity linear strain hardening material, suitable for large deformation.)

ldpc的解码程序,matlab实现，已实现，译码速度快(ldpc decoding process, matlab implementation, has achieved fast decoding)

卡尔曼滤波算法，英文文章原文，适合初学者。(Kalman filter algorithm, the English text, suitable for beginners.)

说明：  vc++调用MATLAB源程序，vc++调用MATLAB源程序，(vc++ to call MATLAB source code, vc++ to call MATLAB source,)

采用改进的直接法在matlab中进行功率谱密度计算(Calculating the direct method using the improved power spectrum density in matlab)

audio card enumerate searching ok. for multimedia developing project. thank you

说明：  经典图书Courant, Hilbert - Methods of Mathematical Physics 第二卷，50年不倒的经典图书，值得一看，是学习数学物理方法的经典名著(Classic books Courant, Hilbert- Methods of Mathematical Physics II, 50 years will not be brought down classic books, worth a visit is to study methods of mathematical physics classics)

说明：  三体问题粒子轨迹图。设正电荷在（-1，0）（1，0）处，电子初始位置根据设定。(three body problem. Positive particle is placed on （-1，0）（1，0）. This program will give the trace of the electron under selected initial position.)

说明：  自己编写的使用聚类方法进行彩色图象分割 效果还可以(themselves prepared for the use of clustering methods color image segmentation can also effect)

Good book about Matlab and optics
