    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。 k\8]fh)J\7  
    y=_8ae}aD~  
    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: (%=[J/F/  
    enableservice('AutomationServer', true) U6;,<-bL  
        enableservice('AutomationServer') g)c<\%  
    H(GWC[tv  
    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 5TqB&GP0  
    M@ILB-H  
    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: d%FD =wm  
    1. 在FRED脚本编辑界面找到参考. owHhlS{  
    2. 找到Matlab Automation Server Type Library jHBzZ!<  
        3. 将名字改为MLAPP {gT2G*Ed^Z  
         T2|dFKeWG  
         =:OS"qD3l  
    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。 }wJ-*By{+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Goa0OC,  
    1. 创建Matlab服务器。 ]f#1G$  
    2. 移动探测面对于前一聚焦面的位置。 W'WZ@!!  
    3. 在探测面追迹光线 wN'Q\l+  
    4. 在探测面计算照度 N]f"+  
    5. 使用PutWorkspaceData发送照度数据到Matlab I/:M~ b  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 N) D;)ZH  
    7. 用Matlab画出照度数据 }{/3yXk[G  
    8. 在Matlab计算照度平均值 w9h`8pt  
    9. 返回数据到FRED中 &qKJN#NM@
