    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。 7'Y 3T[  
    )Y}t~ Zfx  
    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: VlRN  
    enableservice('AutomationServer', true) SdBv?`u|g  
    enableservice('AutomationServer') cOcF VPQ  
    //]g78]=O  
    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 dX{|-;6vm  
    &Z/aM?  
    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: |8PUmax  
    1. 在FRED脚本编辑界面找到参考. A-1Wn^,> *  
    2. 找到Matlab Automation Server Type Library 4\4onCzuT  
    3. 将名字改为MLAPP @B %m,Mx  
    ]N_(M   
    vt<r_&+ pJ  
    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。 ~4y&]:I

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >J^bs &j  
    1. 创建Matlab服务器。 >(S4h}^I  
    2. 移动探测面对于前一聚焦面的位置。 H_m(7@=  
    3. 在探测面追迹光线 V|KYkEl r1  
    4. 在探测面计算照度 u@5vK2  
    5. 使用PutWorkspaceData发送照度数据到Matlab i`)bn 1Xm  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [H)NkR;I  
    7. 用Matlab画出照度数据 iM+K&\{_h  
    8. 在Matlab计算照度平均值 [>QV^2'Z  
    9. 返回数据到FRED中 h!ZEZ|{
