    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。 jg2 UX   
    CcF$?07 i  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: &b!L$@6  
    enableservice('AutomationServer', true) 6??o(ziK$  
        enableservice('AutomationServer') PvmmyF  
    T{9pNf-  
    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 , 7` /D

    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: w$ zX.;s  
    1. 在FRED脚本编辑界面找到参考. 'brt?oZ%  
    2. 找到Matlab Automation Server Type Library 608}-J=3#  
        3. 将名字改为MLAPP $-HP5Kj(k-

    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。 r>!$eqX_

    1. 创建Matlab服务器。 X# 625h  
    2. 移动探测面对于前一聚焦面的位置。 (P( =6-0

    4. 在探测面计算照度 Iq76JJuCb  
    5. 使用PutWorkspaceData发送照度数据到Matlab ' 7lHWqN<  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 x,CTB
