说明：  LM莱文博格马夸特优化算法，python语言(this is a file of LM algorithm which was wroten by python language)

用ABAQUS及其子程序解决热冲压热力耦合问题(Subroutine with ABAQUS and hot stamping coupled thermal problem solving)

计算颤振，使用非定长气动力的方法进行计算，准确可靠(Calculated flutter, the use of non-fixed-length aerodynamic calculation, accurate and reliable)

使用奇异值分解来帮助求解最小二乘问题，特别是在方程系数矩阵不满秩的情况下。(SGELSD computes the minimum-norm solution to a real linear least * squares problem: * minimize 2-norm(| b- A*x |) * using the singular value decomposition (SVD) of A. A is an M-by-N * matrix which may be rank-deficient.)

Amplitude of Explosion.In contrast to the design of sparks number, the am-plitude of a good firework explosion is smaller than that of a bad one. Amplitudeof explosion for each firework is defined as follows

经典R-K法，通过它可以计算一些简单的常微分方程的数值解(Classical RK method, which can be calculated by simple numerical solution of ordinary differential equations)
