    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。 %7(kP}y*  
    =(|xU?OL  
    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: a:-)+sgHw  
    enableservice('AutomationServer', true) HL(U~Q6JQ  
    enableservice('AutomationServer') s7.p$r  
    2 %{YYT   
    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 "Ql}Y1

    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: KYkS6|A  
    1. 在FRED脚本编辑界面找到参考. M)`HK .  
    2. 找到Matlab Automation Server Type Library S}m$,<x  
    3. 将名字改为MLAPP 2-$bh

    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。 Tbi]oB#

    2. 移动探测面对于前一聚焦面的位置。 y NrinYw  
    3. 在探测面追迹光线 Vedyy\TU  
    4. 在探测面计算照度 dq YDz  
    5. 使用PutWorkspaceData发送照度数据到Matlab wUK7um  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %_b^!FR  
    7. 用Matlab画出照度数据 $>'")7z  
    8. 在Matlab计算照度平均值 lJ:M^.Em0  
    9. 返回数据到FRED中 XdGpW
