    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。 Y=sRVypJ  
    b[$%Wg  
    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: 8s-RNA>7^  
    enableservice('AutomationServer', true) ?/9]"HFHN  
    enableservice('AutomationServer') eft-]c+*0  
    S,fMGKcq  
    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 g2^7PtJg  
    {6^c3R[  
    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: }OJ*o  
    1. 在FRED脚本编辑界面找到参考. aj51%wKMb:  
    2. 找到Matlab Automation Server Type Library E)3B)(@&P  
    3. 将名字改为MLAPP quN7'5ZC[

    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。 d%Jl9!u

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5)' _3r  
    1. 创建Matlab服务器。 TyD*m$`y  
    2. 移动探测面对于前一聚焦面的位置。 h#@l'Cye  
    3. 在探测面追迹光线 ( t#w@<  
    4. 在探测面计算照度 4*&x% ~*  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z2)f$ c  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 TC?kuQI  
    7. 用Matlab画出照度数据 h>sz@\{  
    8. 在Matlab计算照度平均值 I.r &;   
    9. 返回数据到FRED中  ^ 'FC.
