说明：   这是几个常用的测试函数，通过这个测试函数可以比较算法性能的优劣。(This is a test of several commonly used functions, through this test function can compare the algorithm performance is good or bad.)

thermal damage abaqus-umat subroutine

包括广义互相关函数GCC时延估计，通过matlab代码，计算加权加速度。( Including the generalized cross-correlation function GCC time delay estimation, By matlab code, Weighted acceleration.)

说明：  分维反映了复杂形体占有空间的有效性，它是复杂形体不规则性的量度。它与动力系统的混沌理论交叉结合，相辅相成。它承认世界的局部可能在一定条件下或过程中，在某一方面（形态，结构，信息，功能，时间，能量等）表现出与整体的相似性，它承认空间维数的变化既可以是离散的也可以是连续的，进而拓展了视野。(Fractal dimension reflects the validity of space occupied by complex bodies, which is a measure of irregularity of complex bodies. It combines with chaos theory of dynamic system and complements each other. It recognizes that the part of the world may be similar to the whole in certain conditions or processes (form, structure, information, function, time, energy, etc.). It recognizes that the change of spatial dimension can be discrete or continuous, thus expanding the horizon.)

针对于对一般矩阵的求逆，或对复杂系统的求逆(Aimed at the general matrix inverse or inverse complex systems)

反密法在数值计算中的地位就不用我来一一列举了，此程序就可以轻易的使其实现。(anti-secret numerical calculation method in the position I would not have to list them one by one, this procedure can easily achieve it.)

采用QR分解方法计算矩阵特征值和特征向量(computes a partial Schur decomposition of a square matrix or operator)

高光谱解混合方法，变分增强拉格朗日线性解混合方法。(A Variable splitting Augmented Lagragian Approach to Linear Spectral Unmixing)

在计算流体力学中，多项流中有相变时，基于温度的相变UDF(Mass based on the temperature of the phase change in the UDF)

用SVD奇异值分解法和阻尼最小二乘算法解决地球物理反问题，程序比较简单易懂(Using SVD, singular value decomposition method and damped least-squares algorithm to solve geophysical inverse problem, the procedure is relatively simple to understand)
