    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。 }M &hcw<  
    J:0`*7  
    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: #g]eDU-[  
    enableservice('AutomationServer', true) Rzxkz  
    enableservice('AutomationServer') c4M]q4]F  
    CFG(4IMx  
    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 {#&jW  
    <4%PT2R  
    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: r-5xo.J'  
    1. 在FRED脚本编辑界面找到参考. }PzHtA,V  
    2. 找到Matlab Automation Server Type Library 3j w4#GW  
    3. 将名字改为MLAPP ]%[.>mR  
    `,Y/!(:;  
    F*=}}H/  
    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。 92Rm{n

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .>@]Im  
    1. 创建Matlab服务器。 9Nu:{_YoP  
    2. 移动探测面对于前一聚焦面的位置。 td|O#R  
    3. 在探测面追迹光线 @<B$LJ|jdG  
    4. 在探测面计算照度 j_}f6d/h  
    5. 使用PutWorkspaceData发送照度数据到Matlab z`Xc] cPi  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 I1!m;5-c9k  
    7. 用Matlab画出照度数据 g>-u9%aa  
    8. 在Matlab计算照度平均值 R^Y _i  
    9. 返回数据到FRED中 [+b&)jN*2
