ABAQUS中各种不同本构的内聚力单元fortran用户子程序(ABAQUS in a variety of constitutive cohesive unit fortran user subroutines)

利用c语言编写，编译成动态链接库而成的matlab整数规划工具箱,包含c语言源程序，(use of language, compiled DLL from the Matlab Integer Programming Toolbox contains language source c,)

说明：  c语言编写的高效用LU分解法求任意维数的矩阵的逆，它是经典书籍《算法导论》（第二版）中矩阵求逆的c语言实现。 (The algorithm of matrix inverse is based on LU decomposition which is proposed by the book of introduction to algorithm (second edition).)

利用拉格朗日松弛法求解机组组合问题，考虑领域搜索的随机性(Using Lagrangian relaxation method to solve the unit combination problem, considering the randomness of the search field)

此为基于图像配准的傅立叶变换源代码，已精心调试过，请放心使用.(This is the image registration based on the Fourier Transform source code, has been painstakingly debugging, please rest assured that use.)

轨迹跟踪卡尔曼滤波建立在线性代数和隐马尔可夫模型(hidden Markovmodel)上(The trajectory tracking Calman filter is based on linear algebra and hidden Markov models (hidden, Markovmodel))

fluent udf 壁面热流通量随时间的变化。 调用fluent udf 里面的宏运算。(fluent udf wall heat flux changes with time. Call fluent udf inside the macro operator.)

本程序包括：DFT（离散傅里叶变换），FFT（快速傅里叶变换），IFFT（快速傅里叶逆变换），conv（卷积：圆周卷积、线性卷积），主要应用于信号处理，既可以对实序列做上述操作，也可以对复序列。(This process includes: DFT (Discrete Fourier Transform), FFT (fast Fourier transform), IFFT (inverse fast Fourier transform), conv (convolution: circular convolution, linear convolution), mainly used signal processing, either on the actual sequence to do the operation, can also be complex sequence.)

基于二阶锥规划的旁瓣抑制滤波器的设计仿真，其中包括m序列，失配滤波器设计，并且考虑增益处理损失。(Based on SOCP sidelobe suppression filter design simulation, including m-sequence mismatch filter design, and to consider the loss of gain processing.)
