    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。 Q,3kaR@O  
    OcT Wq  
    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: g0B] ;Y>(  
    enableservice('AutomationServer', true) Hr?lRaV  
    enableservice('AutomationServer') # e? B  
    COh#/-`\1  
    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 ET}Z>vU}+  
    4z<c8 E8  
    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: J&A1]T4d  
    1. 在FRED脚本编辑界面找到参考. {`!6w>w0  
    2. 找到Matlab Automation Server Type Library KU|W85ye  
    3. 将名字改为MLAPP @z1QoZ^w  
    A6z ,6v6  
    $${I[2 R)  
    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。 jIs>>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w"' Pn`T  
    1. 创建Matlab服务器。 l U/Xi  
    2. 移动探测面对于前一聚焦面的位置。 cGV%=N^BE<  
    3. 在探测面追迹光线 L`nW&; w'  
    4. 在探测面计算照度 t\Vng0  
    5. 使用PutWorkspaceData发送照度数据到Matlab syX?O'xJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  =yod  
    7. 用Matlab画出照度数据 jEBn"]\D  
    8. 在Matlab计算照度平均值 r2RJb6  
    9. 返回数据到FRED中 VIAq$iu7
