    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。 T3NH8nH9"z  
    E[Q2ZqhgbP  
    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: BtrMv6  
    enableservice('AutomationServer', true) Rn*@)5  
    enableservice('AutomationServer') !u;gGgQF  
    DQ@M?~1hp  
    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 mu2|%$C;$

    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: &2nICAN[  
    1. 在FRED脚本编辑界面找到参考. ! u@JH`  
    2. 找到Matlab Automation Server Type Library ~^PNMZk  
    3. 将名字改为MLAPP \]0#jI/:  
    y&V%xE/  
    <v!jS=T  
    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。 pVM1%n:#

    现在将脚本代码公布如下,此脚本执行如下几个步骤: hC4 M}(XM  
    1. 创建Matlab服务器。 A ^t _"J  
    2. 移动探测面对于前一聚焦面的位置。 07]9VJa  
    3. 在探测面追迹光线 Pk;1q?tGw  
    4. 在探测面计算照度 'Ck:=V%}g  
    5. 使用PutWorkspaceData发送照度数据到Matlab .u'MMe>^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Jn%Etz-  
    7. 用Matlab画出照度数据 T$sm}=  
    8. 在Matlab计算照度平均值 NHcA6y$Cz  
    9. 返回数据到FRED中 i91k0q*di
