    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。 1*yxSU@uY  
    p<{P#?4 g  
    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: E]rXp~AZm  
    enableservice('AutomationServer', true) & W od  
        enableservice('AutomationServer') ^?Mp(o  
    rVqQo` K\  
    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 6^WNwe\

    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: K6t"98  
    1. 在FRED脚本编辑界面找到参考. '.1P\>x!]  
    2. 找到Matlab Automation Server Type Library .whi0~i  
        3. 将名字改为MLAPP $3 P De  
         W-l+%T!  
         #|ts1lD#ah  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 y$\tqQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: p X{wEc6}  
    1. 创建Matlab服务器。 gDVsi  
    2. 移动探测面对于前一聚焦面的位置。 [9${4=Kq  
    3. 在探测面追迹光线 b9RHsr]V  
    4. 在探测面计算照度 vI I{i  
    5. 使用PutWorkspaceData发送照度数据到Matlab &F uPd}F  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 +7}^Y}(  
    7. 用Matlab画出照度数据 $j.;$~F  
    8. 在Matlab计算照度平均值 hNM8H  
    9. 返回数据到FRED中 n82tZpn
