    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。 QM* T?PR  
    Rj4C-X 4=  
    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: 1= 7ASS9  
    enableservice('AutomationServer', true) ;b:'i& r  
    enableservice('AutomationServer') D6H?*4f]  
    R7U%v"F>`  
    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 O@4J=P=w  
    )$1>6C\  
    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: C<3<,~gI  
    1. 在FRED脚本编辑界面找到参考. k}p8"'O  
    2. 找到Matlab Automation Server Type Library s2<[@@@q  
    3. 将名字改为MLAPP 6M. |W;

    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。 UfPHV%Wd

    &^#u=w?^x  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: 'A^q)hpax  
    1. 创建Matlab服务器。 3 z(4axH'  
    2. 移动探测面对于前一聚焦面的位置。 HFI0\*xn(  
    3. 在探测面追迹光线 dJ m9''T')  
    4. 在探测面计算照度 `CH,QT7e  
    5. 使用PutWorkspaceData发送照度数据到Matlab oda,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 aZCq{7Xs  
    7. 用Matlab画出照度数据 '5 ~cd  
    8. 在Matlab计算照度平均值 fggs ;Le  
    9. 返回数据到FRED中 gFKJbjT|
