基于MATLAB/Simulink的汽车ABS半实物仿真,本文所研究的是一种基于MATLAB/Simulink的汽车防抱死刹车系统（ABS）的半实物仿真的方法。本方法利用Simulink提供的模型建立车辆的传动系模型、自动变速箱模型和ABS模型等。所建成的这套半实物仿真系统既可在软件环境下对汽车进行仿真，也可以通过I/O接口与ABS系统相连接以观察系统的仿真效果，检验控制算法的合理性。通过合理改变相应参数，本系统还可以模拟实际汽车在不同工况下的工作情况，极大提高了汽车电子设备的研发工作的效率。同时，本系统也可用于教学演示。 ()

本程序用于在给定风向的情况下，计算风从某点传播至另外一点的最短距离(This procedure is used in the case given Winds calculate the wind is propagated to another point of the shortest distance from a certain point)

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出.以第1边界条件为例,用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组.通过Matlab编制三次样条函数的通用程序,可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图.(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. Boundary conditions in the first example, the second derivative with node represents a cubic spline interpolation function, solving equations associated with catch-up method group. preparation of common procedures cubic spline function through Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation has been calculated and displayed for each sub-interval graphs.)
