    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。 |47 2X&e  
    LVL#qNIu  
    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: =2} bQW  
    enableservice('AutomationServer', true) 9R&.$5[W(s  
    enableservice('AutomationServer') M,Lq4bz  
    Q H>g-@  
    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 a^VI)

    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: 7CX5pRNL  
    1. 在FRED脚本编辑界面找到参考. -}8r1jQH;  
    2. 找到Matlab Automation Server Type Library X-j<fX_  
    3. 将名字改为MLAPP Vu<mOuh

    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。 E6-~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: q1|@v#kH6  
    1. 创建Matlab服务器。 _e|-O>#pl  
    2. 移动探测面对于前一聚焦面的位置。 ZalL}?E ?  
    3. 在探测面追迹光线 X{h[    
    4. 在探测面计算照度 H;FzWcm  
    5. 使用PutWorkspaceData发送照度数据到Matlab `_J>R  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 M IUB]  
    7. 用Matlab画出照度数据 | Y(  
    8. 在Matlab计算照度平均值 ~AF' 6"A  
    9. 返回数据到FRED中 v6T<K)S
