    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。 @?"t&h  
    G6x2!Ny  
    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: "Q<*H<e  
    enableservice('AutomationServer', true) Yg14aKZl  
    enableservice('AutomationServer') hk1jxnQ h  
    MHKB:t]hA  
    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 T89VSB~  
    Li\BRlebR{  
    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: uDi#a~m@  
    1. 在FRED脚本编辑界面找到参考. E|Z7art  
    2. 找到Matlab Automation Server Type Library Sf0[^"7  
    3. 将名字改为MLAPP 4lfJc9J  
    W'9=st'

    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。 QabYkL5@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^@..\X9  
    1. 创建Matlab服务器。 D?"TcA  
    2. 移动探测面对于前一聚焦面的位置。 F /:2+  
    3. 在探测面追迹光线 gJ>HFid_C  
    4. 在探测面计算照度 :j2_Jn4UP  
    5. 使用PutWorkspaceData发送照度数据到Matlab \4`2k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 p,w6D,h  
    7. 用Matlab画出照度数据 SbW6O_   
    8. 在Matlab计算照度平均值 L&nGjC+Lr  
    9. 返回数据到FRED中 XL7jUi_4:L
