    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。 U{.+*e18  
    gs)%.k[BqG  
    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: ` Mv5!H5l  
    enableservice('AutomationServer', true) '3Y0D1`v  
    enableservice('AutomationServer') fM zAf3  
    S(YHwH":  
    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 2t~7eI%d  
    {jCu9 ]c!  
    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: MWp\D#H  
    1. 在FRED脚本编辑界面找到参考. Ve')LY<  
    2. 找到Matlab Automation Server Type Library (h8hg+l o  
    3. 将名字改为MLAPP 5Rt0h$_J

    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。 aL$c).hq0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: NUO,"Bqq  
    1. 创建Matlab服务器。 Y+Q,4s  
    2. 移动探测面对于前一聚焦面的位置。 [{fF)D<tC  
    3. 在探测面追迹光线 9-e[S3ziM  
    4. 在探测面计算照度 _tR.RAaa"  
    5. 使用PutWorkspaceData发送照度数据到Matlab xN":2qy#T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Z-;uzx  
    7. 用Matlab画出照度数据 M,v@G$pW  
    8. 在Matlab计算照度平均值 &t=>:C$1Y  
    9. 返回数据到FRED中 3K;b~xg`nw
