    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。 9j1 tcT  
    ;h4w<OqcM  
    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: )C>M74Bt  
    enableservice('AutomationServer', true) %)L|7v<  
    enableservice('AutomationServer') Ekz)Nh)vGR  
    ?r R, h{~  
    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 @qB1:==@7  
    FD^s5>"Y+  
    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: nn/_>%Y  
    1. 在FRED脚本编辑界面找到参考. $,jynRk7q  
    2. 找到Matlab Automation Server Type Library .*L_*}tno  
    3. 将名字改为MLAPP W4=<hB

    !}Ty"p`  
    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。 `BY&&Bv#?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: yQ+C}8r5  
    1. 创建Matlab服务器。 "3VMjF\  
    2. 移动探测面对于前一聚焦面的位置。 E" b" VB  
    3. 在探测面追迹光线 / Hexv#3  
    4. 在探测面计算照度 67dp)X  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3o^  oq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 sme!!+Rd  
    7. 用Matlab画出照度数据 OEs!H]v  
    8. 在Matlab计算照度平均值 q}%;O >Z  
    9. 返回数据到FRED中 &;oWmmvz{
