    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。 Ucdj4[/,h  
    v4Ga0]VN$8  
    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: ?!VIS>C(  
    enableservice('AutomationServer', true) <3okiV=ox  
    enableservice('AutomationServer') FG@ -bV  
    &o3K%M;C?  
    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 !? 5U|  
    $gpG%Qj  
    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: KvPX=/&Zu  
    1. 在FRED脚本编辑界面找到参考. a`(a)9i  
    2. 找到Matlab Automation Server Type Library p4K.NdUH  
    3. 将名字改为MLAPP h*B|fy4K9U  
    ULH0'@BJ  
    C0*@0~8$9  
    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。 ]rN5Ao}2

    现在将脚本代码公布如下,此脚本执行如下几个步骤: qmy%J  
    1. 创建Matlab服务器。 Mwp$  
    2. 移动探测面对于前一聚焦面的位置。 3q:n'PC)C  
    3. 在探测面追迹光线 K+=+?~  
    4. 在探测面计算照度 sOCs13A"  
    5. 使用PutWorkspaceData发送照度数据到Matlab l`-bFmpA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 t*<#<a  
    7. 用Matlab画出照度数据 wd(Hv  
    8. 在Matlab计算照度平均值 VdSv  
    9. 返回数据到FRED中  y! .J
