    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。 &2pM3re/f  
    .6#2i <oPW  
    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: _>64XUZ<n  
    enableservice('AutomationServer', true) qrh7\`,.m/  
    enableservice('AutomationServer') rdg1<Z  
    imQNfNm  
    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 n\9*B##

    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: HX*U2<^  
    1. 在FRED脚本编辑界面找到参考. CFxs`C^  
    2. 找到Matlab Automation Server Type Library dUSuhT  
    3. 将名字改为MLAPP f` J"A:

    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。 ^o:5B%}#[

    现在将脚本代码公布如下,此脚本执行如下几个步骤: W#\4"'=I  
    1. 创建Matlab服务器。 o*'3N/D~  
    2. 移动探测面对于前一聚焦面的位置。 5]+eLKXB  
    3. 在探测面追迹光线 ~'iuh>O)  
    4. 在探测面计算照度 $hh=-#J8  
    5. 使用PutWorkspaceData发送照度数据到Matlab q1Mk_(4oJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 '9XwUQx  
    7. 用Matlab画出照度数据 \v Go5`  
    8. 在Matlab计算照度平均值 ElxbHQj6  
    9. 返回数据到FRED中 i.&16AY
