    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。 -aec1+o  
    +i K.+B  
    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: HF0J>Clq  
    enableservice('AutomationServer', true) UHxXa*HyI  
        enableservice('AutomationServer') 2p'qp/  
     /h   
    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 ousoG$Pc  
    fw-LZ][  
    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: t/y0gr tm6  
    1. 在FRED脚本编辑界面找到参考. XLOk+Fn  
    2. 找到Matlab Automation Server Type Library b ~F8 5U2  
        3. 将名字改为MLAPP -o=qYkyLK  
         :@n e29,}  
         =NlAGzv!w  
    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。 X\flx~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: U?.VY@  
    1. 创建Matlab服务器。 1tfm\/V}ho  
    2. 移动探测面对于前一聚焦面的位置。 i5:fn@&  
    3. 在探测面追迹光线 =G*<WcR  
    4. 在探测面计算照度 WJ/&Ag1  
    5. 使用PutWorkspaceData发送照度数据到Matlab ZfIQ Fh>  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 X4 xnr^  
    7. 用Matlab画出照度数据 E?%rmdyhL!  
    8. 在Matlab计算照度平均值 edbzg #wy  
    9. 返回数据到FRED中 a N_M
