    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。 [-`s`g-  
    BgN^].z&  
    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: ;+DMv5A "  
    enableservice('AutomationServer', true) Obu 6k[BE.  
    enableservice('AutomationServer') 37n2#E  
    .`*;AT  
    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 6x5Q*^w  
    :bo2H[U+  
    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: 4iSN.nxIZ  
    1. 在FRED脚本编辑界面找到参考. DmWa!5  
    2. 找到Matlab Automation Server Type Library +dCR$<e9r  
    3. 将名字改为MLAPP `4ga~Ch

    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。 b4$g$()

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;B< rw ^h5  
    1. 创建Matlab服务器。 m[l&&(+J,  
    2. 移动探测面对于前一聚焦面的位置。 +-x+c: IxA  
    3. 在探测面追迹光线 A?-t`J  
    4. 在探测面计算照度 )(d~A?~  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6wOj,}2Mn  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )4o k@^.  
    7. 用Matlab画出照度数据 }<z [t5  
    8. 在Matlab计算照度平均值 LvGo$f/9  
    9. 返回数据到FRED中 ]c\`EHN
