    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。 >(sS4_O7N  
    = @FT$GQ  
    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: U/7jK40  
    enableservice('AutomationServer', true) A\ tBmL_s  
    enableservice('AutomationServer') O [=W%2I!i  
    eE{ 2{C  
    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 qz!^< M  
    26j-1c!NGd  
    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: ~Oi.bP<,  
    1. 在FRED脚本编辑界面找到参考. !Z;Nv  
    2. 找到Matlab Automation Server Type Library ;[|+tO_  
    3. 将名字改为MLAPP *Ym+xu_5

    % <h2^H\O  
    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。 gOaK7A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6p 14BruV  
    1. 创建Matlab服务器。  GU xhn  
    2. 移动探测面对于前一聚焦面的位置。 *`tQX$F  
    3. 在探测面追迹光线 \9} -5  
    4. 在探测面计算照度 >SD?MW 1E  
    5. 使用PutWorkspaceData发送照度数据到Matlab EhN@;D+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?Y9VviC  
    7. 用Matlab画出照度数据 R7x*/?  
    8. 在Matlab计算照度平均值 'qidorT>N  
    9. 返回数据到FRED中 %@;xbKj
