    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 xkR--/f  
    >nmby|XtW  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: @O+yxGA  
    enableservice('AutomationServer', true) I@P[}XS  
    enableservice('AutomationServer') "UVqkw,vt  
     r(pp =  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ,c"_X8Fkx$  
    NGB%fJ  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: #M*h)/d[A  
    1. 在FRED脚本编辑界面找到参考. 7k{Oae\$  
    2. 找到Matlab Automation Server Type Library Z"#ysC  
    3. 将名字改为MLAPP uy\< t  
    N8(xz-6

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 {:40Jf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9 m&"x/k  
    1. 创建Matlab服务器。 / 3:R{9S%  
    2. 移动探测面对于前一聚焦面的位置。 9,Zg'4",d  
    3. 在探测面追迹光线 PCnE-$QH  
    4. 在探测面计算照度 <uNBsYMuC  
    5. 使用PutWorkspaceData发送照度数据到Matlab `Bx3grZ 7&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Z@&_ T3M  
    7. 用Matlab画出照度数据 {55{ YDqx  
    8. 在Matlab计算照度平均值  fI[tU(x  
    9. 返回数据到FRED中 gT-'#K2qT
