    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。 n&Bolt(tO  
    SV}q8z\  
    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: 12n5{'H2%  
    enableservice('AutomationServer', true) *9 M 5'  
    enableservice('AutomationServer') j38>,9u,  
    h?5$-#q~  
    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 xa#0y   
    y Dg  
    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: ye=*m  
    1. 在FRED脚本编辑界面找到参考. r\Nf309~  
    2. 找到Matlab Automation Server Type Library t-*oVX3D  
    3. 将名字改为MLAPP Is&z~Xy/  
    :SUPGaUJ"  
    e@"1W  
    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。 ,R]hNjs-{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: A ^@:Ps  
    1. 创建Matlab服务器。 (dn(:<_$  
    2. 移动探测面对于前一聚焦面的位置。 K-(k6<h  
    3. 在探测面追迹光线 xzTTK+D@  
    4. 在探测面计算照度 o?@,f/" 5  
    5. 使用PutWorkspaceData发送照度数据到Matlab @ de_|*c  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 c'B6E1}sx  
    7. 用Matlab画出照度数据 |3`Sd;^;  
    8. 在Matlab计算照度平均值 #ak2[UOT  
    9. 返回数据到FRED中 :fz&)e9
