说明：  光流场HS算法，主要用的是差分算法，MATLAB编写(Optical flow field HS algorithm, the main differential algorithm)

傅里叶变换FFT和逆傅里叶变换IFFT 欢迎大家喜欢(FFT and IFFT)

It checks whether the processes r working in safe mode or in Deadlock Condidion.....pls do the modifications as per ur requirement...as it is implemented static

共炮点地震波正演，其中、包括了直达波，反射波，折射波(Common shot point synthesis of reflected wave records)

计算流体力学有限体积法程序开源代码改进版本，增加了湍流模型(An improved Edition of open source computational fluid dynamics finite volume method program, increased turbulence model)

上三角或下三角矩阵也有大部份的元素不储存值（为0），我们可以将它们使用一维阵列来储存以节省储存空间，而对称矩阵因为对称于对角线，所以可以视为上三角或下三角矩阵来储存。(Upper or lower triangular matrix or a large majority of elements are not stored value (0), we can use them to store a one-dimensional array in order to save storage space, and because the symmetrical diagonal symmetric matrix, it can be regarded as the or lower triangular matrix storage.)

截断奇异值分解技术是一种正则化方法，用于不适定问题的数值计算(Truncated Singular Value Decomposition is a regularizaiton method for ill-conditioned problem computation.)
