    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。 {Z;W|w1t  
    />\.zuAr&  
    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: iZ[o2Tre  
    enableservice('AutomationServer', true) t]FFGnBZ  
    enableservice('AutomationServer') 4BuS? #_  
    xPqpNs-,  
    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 -tx)7KV-  
    7w )#[^  
    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: zE.4e&m%Z?  
    1. 在FRED脚本编辑界面找到参考. %{/0K<M  
    2. 找到Matlab Automation Server Type Library Uk ?V7?&  
    3. 将名字改为MLAPP ]@ETQ8QN

    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。 -<&"geJA

    现在将脚本代码公布如下,此脚本执行如下几个步骤: l%B1JGu*F  
    1. 创建Matlab服务器。 a|?CC/Ra  
    2. 移动探测面对于前一聚焦面的位置。 #=t:xEz  
    3. 在探测面追迹光线 IG +nrTY0  
    4. 在探测面计算照度 WP^%[?S2  
    5. 使用PutWorkspaceData发送照度数据到Matlab x)#k$ QU  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @oYq.baHX  
    7. 用Matlab画出照度数据 X?rJO~5  
    8. 在Matlab计算照度平均值 C&Nd|c  
    9. 返回数据到FRED中 & PHHacp
