    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。 !;>j(xc  
    G[GSt`LVS`  
    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: [WW3'= e^  
    enableservice('AutomationServer', true) sk6C/ '0:  
    enableservice('AutomationServer') f!AcBfaLr  
    {94qsVxQZ  
    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 [jU.58*  
    yP. ,Dh s  
    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: ,ir(~g+{g  
    1. 在FRED脚本编辑界面找到参考. F$X"?fj  
    2. 找到Matlab Automation Server Type Library 1%g%I8W%  
    3. 将名字改为MLAPP K 0R<a~

    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。 Fu].%`*xJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <A"[Wk  
    1. 创建Matlab服务器。 "k&QS@l  
    2. 移动探测面对于前一聚焦面的位置。 m`_s_#  
    3. 在探测面追迹光线 j6}/pe*;;T  
    4. 在探测面计算照度 A0JlQE&U  
    5. 使用PutWorkspaceData发送照度数据到Matlab dz_~_|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u)J&3Ah%  
    7. 用Matlab画出照度数据 W~b->F  
    8. 在Matlab计算照度平均值 kbu.KU+  
    9. 返回数据到FRED中 6_}& WjU'
