    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。 [Ls2k&)0  
    _{Fdw  
    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*^,l`C/  
    enableservice('AutomationServer', true) SSA%1l 2!  
        enableservice('AutomationServer') ],fwZd[t  
    rH#c:BwSm  
    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 Le#E! sU  
    / %U~lr  
    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: @wAr[.lZ  
    1. 在FRED脚本编辑界面找到参考. x]mye  
    2. 找到Matlab Automation Server Type Library  q~:'R  
        3. 将名字改为MLAPP y(wqcDok|n  
         (c*7VO;  
         k:+)$[t7  
    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。 {W:)oh>

    1. 创建Matlab服务器。 0.{oA`5N  
    2. 移动探测面对于前一聚焦面的位置。 yEw"8u'  
    3. 在探测面追迹光线 M~g~LhsF  
    4. 在探测面计算照度 y9re17{ X  
    5. 使用PutWorkspaceData发送照度数据到Matlab R>YMGUH~w  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 "k_n+cH%  
    7. 用Matlab画出照度数据 ixI5Xd<  
    8. 在Matlab计算照度平均值 ,nu7r1}  
    9. 返回数据到FRED中 0D]Yz`n3
