    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。 *]h"J]  
    ' Q(kx*;  
    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: SdYb T)y  
    enableservice('AutomationServer', true) WiB~sIp  
        enableservice('AutomationServer') |HYST`  
    E{ e  
    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 g6P^JW}.  
    QG~6mvD  
    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: Njr;Wa.r+  
    1. 在FRED脚本编辑界面找到参考. Zlh 2qq  
    2. 找到Matlab Automation Server Type Library ,Wu$@jD/ ]  
        3. 将名字改为MLAPP njZ vi}m~  
         'UxI-L t  
         s^IC]sW\%  
    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。 Fw{#4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `H>&d K|/  
    1. 创建Matlab服务器。 9L3P'!Z  
    2. 移动探测面对于前一聚焦面的位置。 nTD%i~t~o  
    3. 在探测面追迹光线 z~tdLtcX  
    4. 在探测面计算照度 5@ td0  
    5. 使用PutWorkspaceData发送照度数据到Matlab F E{c{G<  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 83 R_8  
    7. 用Matlab画出照度数据 8!3q:8y8  
    8. 在Matlab计算照度平均值 pU<J?cU8N  
    9. 返回数据到FRED中 wbcip8<t
