    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。 6}oXP_0U  
    go<W( ,O  
    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: }7.PH'.8  
    enableservice('AutomationServer', true) 7?%k7f  
    enableservice('AutomationServer') }x wu*Zx  
    jav#f{'  
    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 mFZ?hOyP.  
    <z!CDg4  
    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: $+I;oHWI  
    1. 在FRED脚本编辑界面找到参考. _n` a`2C|m  
    2. 找到Matlab Automation Server Type Library byfJy^8G  
    3. 将名字改为MLAPP <N9[?g)  
    7[}xP#Z  
    IDG}ZlG  
    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。 4sT88lG4n

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <fFTY130:  
    1. 创建Matlab服务器。 xsMBC  
    2. 移动探测面对于前一聚焦面的位置。 9BuSN*4  
    3. 在探测面追迹光线 <>aw 1WM+  
    4. 在探测面计算照度 fk x \=  
    5. 使用PutWorkspaceData发送照度数据到Matlab '5|h)Q5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #Q`dku%V:  
    7. 用Matlab画出照度数据 O|M{-)  
    8. 在Matlab计算照度平均值 9AJ7h9L  
    9. 返回数据到FRED中 M!XsJ<jN/
