    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。 ^rwSbM$  
    e_], O_ Z  
    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: 2[po~}2-0  
    enableservice('AutomationServer', true) QZr<=}   
        enableservice('AutomationServer') .Qt3!ek  
    a1SOC=.M;  
    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 Hz8`)cv`  
    C8:"+;  
    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: 'cN#rHPB6  
    1. 在FRED脚本编辑界面找到参考. P@YL.'KU)  
    2. 找到Matlab Automation Server Type Library Td*Oljj._U  
        3. 将名字改为MLAPP sK0VT"7K

    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。 &.hRVW(

    1. 创建Matlab服务器。 5iddB $  
    2. 移动探测面对于前一聚焦面的位置。 -5 /v`  
    3. 在探测面追迹光线 ACO4u<M)  
    4. 在探测面计算照度 2j7d$y*'  
    5. 使用PutWorkspaceData发送照度数据到Matlab b',bi.FH  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 6 v^  
    7. 用Matlab画出照度数据 @z)tC@  
    8. 在Matlab计算照度平均值 ZT8J i?_n
