利用matlab实现无约束优化，对不同的函数进行优化，并比较优化结果和运算速度(Matlab unconstrained optimization, optimize and compare different function optimization results and computational speed.)

matlab 模拟退火经典程序，简单但实用，能很好的理解模拟退，里面还有一个无约束优化的例子(matlab classical simulated annealing procedure, a simple but practical, a good understanding of simulation can retire, which have an example of unconstrained optimization)

controlled Half wave rectifier circuit with resistive load with freewheeling diode and gives positive half cycle and block negative half cycle.

IEEE14节点潮流计算程序，可以很好地计算14节点标准系统，收敛性好。(IEEE14 node flow calculation program, 14 compute nodes can be a good standard system, good convergence.)

main_spheretoML是主程序，性能达到最大似然NL检测，调用了spheredecodetoML和spheredecodeinftoML两个子程序(sdinf ml)

直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low-4bit)

很全置信度传播算法，对坐message passing的人很有用(Belief propagation algorithm)
