    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。 5AV5`<r.  
    Q)}_S@v|%  
    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: 5e^t;  
    enableservice('AutomationServer', true) U2  0@B`<  
    enableservice('AutomationServer') E;7vGGf]  
    D;%(Z!  
    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 at_~b Ox6X  
    XI#1)  
    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: O=c^Ak   
    1. 在FRED脚本编辑界面找到参考. 7;H!F!K]  
    2. 找到Matlab Automation Server Type Library Nrp0z:  
    3. 将名字改为MLAPP RtZK2  
    ~4HS 2\  
    u;$g1 3  
    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。 WVPnyVDc

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ZuV/!9qU  
    1. 创建Matlab服务器。 /(#;(]  
    2. 移动探测面对于前一聚焦面的位置。 y8/ 7@qw  
    3. 在探测面追迹光线 saMv.;s 1^  
    4. 在探测面计算照度  [o]^\a y  
    5. 使用PutWorkspaceData发送照度数据到Matlab xE+Nz5F  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1&_9 3  
    7. 用Matlab画出照度数据 Z]H`s{3  
    8. 在Matlab计算照度平均值 @k_xA-a  
    9. 返回数据到FRED中 "o+E9'Dm
