    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。 ol^OvG:TQ  
    _<+!  
    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: 4@u*#Bp`|  
    enableservice('AutomationServer', true) P bj&l0C  
    enableservice('AutomationServer') jav7V"$  
    ==RYf*d  
    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 U,gg@!1GJo  
    ,gVA^]eDh  
    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: ,ZHIXylZ  
    1. 在FRED脚本编辑界面找到参考. -v/1R1$e1  
    2. 找到Matlab Automation Server Type Library c/jU+,_g  
    3. 将名字改为MLAPP %|*tL7  
    N<zD<q  
    \'xF\V  
    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。 `WboM\u

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h8&VaJ  
    1. 创建Matlab服务器。 fZw/kjx@  
    2. 移动探测面对于前一聚焦面的位置。 |C301ENZ  
    3. 在探测面追迹光线 H9?(5  
    4. 在探测面计算照度 E z?O gE{  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5/F1|N4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C< 3` ]l  
    7. 用Matlab画出照度数据 [_Fj2nb*  
    8. 在Matlab计算照度平均值 $Ypt /`  
    9. 返回数据到FRED中 T`mG+"O
