    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。 5Yg'BkEr  
    wcrCEX=I>{  
    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: t URu0`](  
    enableservice('AutomationServer', true) m~iXl,r  
    enableservice('AutomationServer') zU5v /'h>d  
    #3i3G(mQ  
    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 h9t$Uz^N

    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: k0OYJ/  
    1. 在FRED脚本编辑界面找到参考. }~YA5^VQ$  
    2. 找到Matlab Automation Server Type Library qk%;on&`  
    3. 将名字改为MLAPP k$4y9{  
    )X1{  
    }s7$7  
    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。 AHD=<7Rs

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &C `Gg<  
    1. 创建Matlab服务器。 I,E?h?6Y  
    2. 移动探测面对于前一聚焦面的位置。 QE^$=\l0  
    3. 在探测面追迹光线 9 &$y}Y  
    4. 在探测面计算照度 R[zpD%CI  
    5. 使用PutWorkspaceData发送照度数据到Matlab |6.l7u ?d  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LoURC$lS  
    7. 用Matlab画出照度数据 "|x^|n8i  
    8. 在Matlab计算照度平均值 J4k=A7^N  
    9. 返回数据到FRED中 W,K;6TZhh
