    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。 `j2z=5  
    iGp@P=;m  
    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: @!Pq"/  
    enableservice('AutomationServer', true) g_q{3PW.  
    enableservice('AutomationServer') ~p8!Kb6  
    /RMep8 &  
    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 Qejzp/2  
    w?R6$n`  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 2{qoWys8[  
    1. 在FRED脚本编辑界面找到参考. 9:m+mpL=9  
    2. 找到Matlab Automation Server Type Library 3sL#_@+yz  
    3. 将名字改为MLAPP ugL$W@

     [g/g(RL  
    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。 mT9TSW}

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5-sxTp  
    1. 创建Matlab服务器。 sPhh#VCw{  
    2. 移动探测面对于前一聚焦面的位置。 @U9ov >E  
    3. 在探测面追迹光线 [[)HPHSQ  
    4. 在探测面计算照度 %@IR7v~  
    5. 使用PutWorkspaceData发送照度数据到Matlab 'tdjPdw  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w ggl,+7  
    7. 用Matlab画出照度数据 cL}g7D  
    8. 在Matlab计算照度平均值 s*Fmu7o43  
    9. 返回数据到FRED中 rj6wKf z
