    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。 o2W^!#]=  
    E>Lgf&R#W  
    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: H?tX^HO:q  
    enableservice('AutomationServer', true) <_~e/+_.  
    enableservice('AutomationServer') j-9Zzgr  
    h #(J6ht  
    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 :FX|9h  
    }-H)jN^  
    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: -8m3L  
    1. 在FRED脚本编辑界面找到参考. ?yy,3:  
    2. 找到Matlab Automation Server Type Library #MAXH7[  
    3. 将名字改为MLAPP ?OF9{$m3?

    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。 #gSLFM{p

    1. 创建Matlab服务器。 R/Z zmb{  
    2. 移动探测面对于前一聚焦面的位置。 l' 2C/#8F  
    3. 在探测面追迹光线 LZ<^b6Dxk  
    4. 在探测面计算照度 }0~X)Vgm(  
    5. 使用PutWorkspaceData发送照度数据到Matlab }) Zcw1g  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (Fs{~4T  
    7. 用Matlab画出照度数据 J/B`c(  
    8. 在Matlab计算照度平均值 +a0` ,Jc  
    9. 返回数据到FRED中 #dDM "s
