    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。 ~,.;2K73  
    . Gb!mG  
    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: WF<3 7"A@  
    enableservice('AutomationServer', true) 4u#TKr.  
    enableservice('AutomationServer') Hz>Dp !  
    4B)%I`  
    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 0!M'z  
    P=Su)c  
    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: \J(kM,ZJ  
    1. 在FRED脚本编辑界面找到参考. $CZ'[`+  
    2. 找到Matlab Automation Server Type Library i:1 @ vo  
    3. 将名字改为MLAPP e(Rbq8D  
    y2=yh30L0E  
    IRTD(7"oyp  
    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。 Z{1B:aW

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8#/y`ul  
    1. 创建Matlab服务器。  45WJb+$  
    2. 移动探测面对于前一聚焦面的位置。 ilAhw4A  
    3. 在探测面追迹光线 13+. >  
    4. 在探测面计算照度 JX{_,2*$  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^9kx3Pw?8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 uaZHM@D  
    7. 用Matlab画出照度数据 n}c~+ 0`un  
    8. 在Matlab计算照度平均值 $=) Pky-~  
    9. 返回数据到FRED中 KtGbpcS$f
