    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。 sN[@mAoH  
    ={&TeMMA  
    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: D$^7Xhk  
    enableservice('AutomationServer', true) y(p:)Iv  
    enableservice('AutomationServer') N;Gf,pE  
    !gA^$(=:"  
    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 { &JurZ  
    ,y{fqa4  
    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: @v:ILby4-  
    1. 在FRED脚本编辑界面找到参考. D4x'  
    2. 找到Matlab Automation Server Type Library `A}{ I}xq  
    3. 将名字改为MLAPP 5SPl#*W  
    ph$&f0A6Xc  
    qz_TcU'  
    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。 Q:xI} ]FM

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TJGKQyG$L  
    1. 创建Matlab服务器。 {<V|Gr  
    2. 移动探测面对于前一聚焦面的位置。 ,:Y=,[n  
    3. 在探测面追迹光线 eB1eUK>  
    4. 在探测面计算照度 I^C ]6D{  
    5. 使用PutWorkspaceData发送照度数据到Matlab \2VZkVO9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !nD[hI8P  
    7. 用Matlab画出照度数据 t)kr/Z*p\  
    8. 在Matlab计算照度平均值 EPUJa~4  
    9. 返回数据到FRED中 6`PGV+3j
