    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。 PGZ.\i  
    (3YqM7cqt  
    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: 5HP6o  
    enableservice('AutomationServer', true) &Npv~Iy  
    enableservice('AutomationServer') It,m %5 Py  
    .])ubK_9  
    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 n]I_ LlbY  
    ldcYw@KQ  
    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: 7MIu-x|  
    1. 在FRED脚本编辑界面找到参考. fF !Mmm"  
    2. 找到Matlab Automation Server Type Library Gw3eO&X3i  
    3. 将名字改为MLAPP 41 sClC"  
    A-gNfXP,D  
    9hG)9X4  
    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。 W tF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^L}fj$  
    1. 创建Matlab服务器。 }Y\Ayl  
    2. 移动探测面对于前一聚焦面的位置。 aH<BqD[#  
    3. 在探测面追迹光线 U1(<1eTyu  
    4. 在探测面计算照度 /C"dwh"``  
    5. 使用PutWorkspaceData发送照度数据到Matlab l<  8RG@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4~-"k{Xt  
    7. 用Matlab画出照度数据 XE);oL2xP  
    8. 在Matlab计算照度平均值 3c] oU1GfF  
    9. 返回数据到FRED中 oj*5m+:>a
