    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。 d}G."wnG9,  
    J ##X5'a3*  
    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: +_K;Pj]x  
    enableservice('AutomationServer', true) AZ@Zo'  
    enableservice('AutomationServer') [A/+tv  
    Z["nY&.sI  
    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 kj"_Y"q=  
    vxfh1B&  
    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: 9fLP&v  
    1. 在FRED脚本编辑界面找到参考. $ }bC$?^  
    2. 找到Matlab Automation Server Type Library ?;QKe0I^  
    3. 将名字改为MLAPP iPL'JVPZ

    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。 CAObC%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }U1{&4Ph  
    1. 创建Matlab服务器。 4o8HEq!  
    2. 移动探测面对于前一聚焦面的位置。 cB'4{R@e  
    3. 在探测面追迹光线 .aRxqFi_  
    4. 在探测面计算照度 Y2$`o4*3  
    5. 使用PutWorkspaceData发送照度数据到Matlab |?Uc:VFF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 43]&SXprH  
    7. 用Matlab画出照度数据 X-WvKH(=w  
    8. 在Matlab计算照度平均值 !f2>6}hE  
    9. 返回数据到FRED中 f3&//h8
