说明：  FR共轭梯度算法求极小值。y为给定函数，x为函数变量，x0为搜索起始点 返回值fm为极小值，xm为极小值点(FR conjugate gradient algorithm for the minimum. y for a given function, x as a function of variables, x0 the starting point for the search to return to the value of fm for the minimum, xm for the minimum point)

用来实验验证c转换为汇编的效率，本代码为一个简单的小延时，通过不同德c代码，转换成汇编，看他们的大小，和执行效率(C is used to convert the experimental verification of the efficiency of assembly, the code for a simple little delay, through different de c code into assembly, to see their size, and efficiency)

说明：  波形的合成与分解。 用matlab编的。可以合成三角波，方波，并分析它们的频谱。有详细的说明。(Synthesis and decomposition of waveforms. Made use of matlab. Can be synthesized triangular wave, square wave, and an analysis of their spectrum. Is described in detail.)

相参脉冲串复调制信号，仿真图是速度、距离、幅度三维图像，是小学期课程设计的题目。( Complex modulation coherent pulse train signal, FIG simulation speed, distance, amplitude three-dimensional image, Is the topic of the elementary school stage curriculum design.)

说明：  bp神经网络算法的matlab源代码，挺有用的。(bp neural network algorithm matlab source code, quite useful.)

关于球体的RCS计算程序，此程序是由matlab语言编辑的，较为经典。(Sphere on the RCS calculation program, this program is edited by the matlab language, more classic.)

说明：  将标准微粒群算法进行改进，从而解决标准PSO算法的容易陷入局部最优解的情况。(The standard particle swarm algorithm is improved so as to solve the standard PSO algorithm is easy to fall into local optimal solution of the situation.)

采用线性滤波法即AR法模拟脉动风速,计算时间短，模拟效果好(Linear filtering AR simulation fluctuating wind speed)

Gauss-Jordan routine, single RHS

Function to calculate the principal curvatures on a triangular mesh. Approximations of curvature are based on local (N=1) neighborhood elements and vertices. Note: Directions of curvatures aren t calculated appropriately. Will post an updated version once this is implemented. Note that calculations at vertices with few adjacent triangles, and hence few adjacent vertices, are expanded to a greater neighborhood.
