    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。 Ak1f*HGl|  
    ;id  
    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: M"P$hb'F  
    enableservice('AutomationServer', true) `HHbQXB  
    enableservice('AutomationServer') b?Vu9!  
    &'(:xjN  
    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 TM"i9a? ;  
    S#ven&  
    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: 'T.> oP0>  
    1. 在FRED脚本编辑界面找到参考. "r|O /   
    2. 找到Matlab Automation Server Type Library W`;E-28Dg  
    3. 将名字改为MLAPP a#mdD:,cF  
    GHoPv-#  
    K{ 0mb  
    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。 2 OGg`1XX

    现在将脚本代码公布如下,此脚本执行如下几个步骤: gzuM>lf*{  
    1. 创建Matlab服务器。 z?cRsqf  
    2. 移动探测面对于前一聚焦面的位置。 HM<V$ R  
    3. 在探测面追迹光线 j7i[z>:Y  
    4. 在探测面计算照度 *ZY{^f  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6vmkDL8{A8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 m(&ZNZK  
    7. 用Matlab画出照度数据 O[-wm;_(=*  
    8. 在Matlab计算照度平均值 {9)LHX7dN
