A tapered Bar Stiffeness & Displacement Matrix

应用matlab对测井数据进行分析计算，最终实现机械钻速预测(Matlab application for logging data analysis and calculation, and ultimately predict ROP)

matlab 遗传算法GA，粒子群算法PSO,蚁群算法AS 前段时间上智能计算方法实验课上，自己做的程序。帖到这里，希望有人能改进它们，交流经验这样更有价值。 遗传算法解决最小生成树问题，PURFER编码。 粒子群算法做无约束最优化问题。 蚁群算法解决TSP问题。 如果有宝贵经验希望能交流一下，谢谢，呵呵(matlab genetic algorithm GA, particle swarm optimization PSO, ant colony algorithm for calculation of AS some time ago on the intelligent test classes, make their own procedures. Quote here, hope someone can improve them, and exchange of experience which is more valuable. Genetic algorithm to solve the minimum spanning tree problem, PURFER coding. Particle swarm optimization to do unconstrained optimization problem. Ant colony algorithm to solve the TSP problem. If there is hope to exchange our experience, thank you, He He)

the code for four bit qpsk with 90 degrees phase shift with constellation and without constellation of noise is given

说明：  matlab,对解决学习中遇到的实际问题会有很大的帮助(Matlab, learning to solve practical problems encountered in will be a big help)

Sigmoid的参数求解matlab源代码，可以嵌入到各种机器学习问题中使用(Sigmoid parameters Solving Matlab source code, can be embedded into various machines used to study the problem)
