    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。 (DI>5.x"  
    P-9<YN  
    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: 1')%`~  
    enableservice('AutomationServer', true) &Y }N|q-  
        enableservice('AutomationServer') <_7*67{  
    BqT y~{)+  
    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 N0r16# -g  
    ?"g!  
    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:  P Y  
    1. 在FRED脚本编辑界面找到参考. *6VF $/rP  
    2. 找到Matlab Automation Server Type Library 8SGo9[U2  
        3. 将名字改为MLAPP O&Y*pOg  
         /HaHH.e  
         xoN3  
    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。 ml+; Rmvb

    1. 创建Matlab服务器。 5rU[ T ir  
    2. 移动探测面对于前一聚焦面的位置。 r4SXE\ G  
    3. 在探测面追迹光线 ~Yy>zUH^X  
    4. 在探测面计算照度 H5Io{B%=  
    5. 使用PutWorkspaceData发送照度数据到Matlab N(Tz%o4  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Rx}$0c0  
    7. 用Matlab画出照度数据 ;'cN<x)% |
