    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。 VGL!)1b  
    ;)rs#T;$  
    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: F#>^S9Gml  
    enableservice('AutomationServer', true) JQO%-=t  
        enableservice('AutomationServer') :G/.h[\R|  
    ,0fYB*jk  
    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 nNP{>\x;"  
    Ks/Uyu. X  
    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: =5D@~?W ZG  
    1. 在FRED脚本编辑界面找到参考. R1j)0b6cQ%  
    2. 找到Matlab Automation Server Type Library tLc~]G*\`s  
        3. 将名字改为MLAPP }DzN-g<K

    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。 mEVne.D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8pE0ANbq

    2. 移动探测面对于前一聚焦面的位置。 +jrMvk"  
    3. 在探测面追迹光线 [*2|#KSCX  
    4. 在探测面计算照度 qE)G;Y<,1  
    5. 使用PutWorkspaceData发送照度数据到Matlab "PtOe[Xk  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 f^D4aEU  
    7. 用Matlab画出照度数据 $/XR/  
    8. 在Matlab计算照度平均值 Yv7`5b{N.  
    9. 返回数据到FRED中 r<XlIi
