    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。 b}z`BRCc  
    |cbd6e{!  
    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: '%iPVHK7  
    enableservice('AutomationServer', true) (yrh=6=z  
    enableservice('AutomationServer') ks(SjEF  
    6.Ie\5-a;  
    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 GY!C|7kN  
    P~$< X  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: .QWhK|(.!  
    1. 在FRED脚本编辑界面找到参考. `$;+g ,  
    2. 找到Matlab Automation Server Type Library c=p=-j=.J  
    3. 将名字改为MLAPP Rs;15@t@  
    D9ufoa&ua  
    u</8w&!  
    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。 fZryG

    现在将脚本代码公布如下,此脚本执行如下几个步骤: AHh#Fx+K  
    1. 创建Matlab服务器。 Q s(Bnb;  
    2. 移动探测面对于前一聚焦面的位置。 #*$p-I=  
    3. 在探测面追迹光线 @s* ,xHE  
    4. 在探测面计算照度 UGKaOol.  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]?l{j  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y.a]r7  
    7. 用Matlab画出照度数据 5 9 2;W-y  
    8. 在Matlab计算照度平均值 x1[?5n6  
    9. 返回数据到FRED中 #;r]/)>
