    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。 kKjcW` [  
    &SNH1b#>E  
    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: f:y1eLl3  
    enableservice('AutomationServer', true) 'Ebjn>"  
    enableservice('AutomationServer') 6kMkFZ}+  
    O;i0xWUh  
    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 >2= Y 35j  
    RWX!d54&  
    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: <1B+@  
    1. 在FRED脚本编辑界面找到参考. ~mwIr  
    2. 找到Matlab Automation Server Type Library 8!HB$vdw7  
    3. 将名字改为MLAPP 7 \[fjCg\w

    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。 2i;ox*SfpU

    1. 创建Matlab服务器。 8e^uKYR<  
    2. 移动探测面对于前一聚焦面的位置。 Z[ &d2'  
    3. 在探测面追迹光线 G "!v)o  
    4. 在探测面计算照度 SH#*Lc   
    5. 使用PutWorkspaceData发送照度数据到Matlab H5&._  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ok|Dh;1_  
    7. 用Matlab画出照度数据 L &hw- .Q  
    8. 在Matlab计算照度平均值 KV$4}{  
    9. 返回数据到FRED中 D6|-nl
