    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。 >m%\SuXq  
    ~9 K4]5K-  
    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: b Kv9F@  
    enableservice('AutomationServer', true) fv#e 8y  
    enableservice('AutomationServer') Zj!S('hSY  
    _?`3zm4  
    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 DKYrh-MN  
    v ;{s@CM m  
    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: Pp #!yMxBr  
    1. 在FRED脚本编辑界面找到参考. 8vc4J5  
    2. 找到Matlab Automation Server Type Library 1+Ja4`o,iS  
    3. 将名字改为MLAPP Y~bp:FkS

    Ewu 7tq Z  
    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。 Ow mI*`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rzY7f: '  
    1. 创建Matlab服务器。 xlS t  
    2. 移动探测面对于前一聚焦面的位置。 ,8EeSnI  
    3. 在探测面追迹光线 W<v?D6dFq  
    4. 在探测面计算照度 ]r6,^"  
    5. 使用PutWorkspaceData发送照度数据到Matlab nA5v+d-<T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &c?-z}=G  
    7. 用Matlab画出照度数据 8_mdh+  
    8. 在Matlab计算照度平均值 \S1WF ?<,  
    9. 返回数据到FRED中 Fg`r:,(a
