Calculate Trunking Efficiency with MatLab

虚拟激励法的实现，4自由度的随机振动问题，包含详细说明，对出学者有很好启示作用！(The realization of the virtual excitation method, 4 degrees of freedom random vibration problems, including details of the scholars have a good inspiration!)

matlab仿真命令集 包括仿真命令、线性化和整理命令、构建模型命令等(Matlab simulation command set includes orders simulation, linear and finishing order, constructing model orders)

sift算子中高斯金字塔和DOG的生成，只是该算子的最初步骤(sift operator：the generation of Gaussian pyramid and DOG。it is only the first steps)

最小二乘拟合，包括3次，9次，15次曲线拟合(Least-squares fit, including three times, nine times, 15 times Curve Fitting)

产生混沌时间序列，Logistic映射Henon映射等。(Chaotic time series, Logistic mapping Henon mapping.)

灰度变换，用了线性的两种变换 一种是分段的一种是不分段的 用matlab实现了灰度的变换(Gray level transformation, two transformations with a linear one is not a sub-segmented by gray-scale transform matlab implements)

无功优化的最优潮流程序，可以自行替换ieee数据(Optimal Power Flow)

Evaluate the value of an arithmetic expression in Reverse Polish Notation. Valid operators are +, -, *, /. Each operand may be an integer or another expression. Some examples: [ 2 , 1 , + , 3 , * ] -> ((2 + 1) * 3) -> 9 [ 4 , 13 , 5 , / , + ] -> (4 + (13 / 5)) -> 6 分析：这一题就是写程序计算逆波兰式的结果，遍历表达式，碰到操作数入栈，碰到操作符就从栈顶取出两个操作数，再将计算后的结果入栈，最后栈中剩余的唯一操作数就是计算结果。(.
