    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。 "jL1. 9%"  
    8P,l>HA  
    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: F:M>z=  
    enableservice('AutomationServer', true) -$+,]t^GV  
    enableservice('AutomationServer') >=if8t!  
    )@}A r  
    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 U/ ?F:QD4

    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: lijB#1<8*  
    1. 在FRED脚本编辑界面找到参考. ,*/Pg 52?  
    2. 找到Matlab Automation Server Type Library 7MY)\aH  
    3. 将名字改为MLAPP ,{k<JA {

    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。 WgE@89

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?4^} ;wDb2  
    1. 创建Matlab服务器。 N99[.mErU  
    2. 移动探测面对于前一聚焦面的位置。 p-.Ri^p   
    3. 在探测面追迹光线 :'Zx{F`  
    4. 在探测面计算照度 {'NBp0i  
    5. 使用PutWorkspaceData发送照度数据到Matlab mge#YV::  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~?gzq~~t  
    7. 用Matlab画出照度数据 E W`W~h[  
    8. 在Matlab计算照度平均值 *oCxof9JA  
    9. 返回数据到FRED中 a$d:_,\ "
