matlab最速下降法，简单的求二次函数的hesse矩阵(steep decent method)

MATLAB教学用书或高等数学、线性代数、计算方法、复变函数、概率统计、数学规划、偏微分方程解法以及动态仿真等课程的教学辅导书，也可作为科研人员及工程计算人员学习和使用MATLAB的参考书(MATLAB books or teaching advanced mathematics, linear algebra, computational methods, complex variable functions, probability and statistics, mathematical programming, dynamic simulation of partial differential equation, and counseling and other teaching books, can also be calculated as the scientific and engineering staff to learn and reference books to use MATLAB)

对“data4.m”数据，采用两种聚类算法聚类，并对结果进行分析。(Uses two types of clustering algorithm clustering "data4.m" data, the results were analyzed.)

boost变换器是一种DCDC升压装置，使用及其广泛，而且性能稳定。该matlab仿真模型是电压模式控制下的boost变换器模型，保持输出电压稳定。该模型应用simulink仿真。效果挺好。(Boost converter is a kind of DCDC booster device, use and wide, and stable performance. The matlab simulation model is under the control of voltage mode boost converter model, keep the output voltage stability. )

船舶运动模拟，需要的赶紧下，过期不候，很实用，ＯＤＥ求解ＯＤＥ(Ship motion simulation, need hurry, without waiting, very practical, ODE solver ODE)

说明：  乘积的最后三位的值只与乘数和被乘数的后三位有关，与乘数和被乘数的高位无关，利用此来求尾数(The last three values of the product only with the multiplier and the multiplicand on the back three, with a high multiplier and the multiplicand has nothing to do, take advantage of this to seek mantissa)

lingo 程序，此为工件排序的代码,可以归为运筹学的时间序列问题。(lingo （how to range）)

说明：  这是独立分析针对图像分离的代码，很清楚的。(This is a separate code for the image of the independent analysis, it is clear.)

PID control simulation(matlab simulation for pid controller)
