    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。 3? +Hd  
    #Mw8^FST  
    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: b;UJ 88  
    enableservice('AutomationServer', true) pz>>)c`  
    enableservice('AutomationServer') VW4r{&rS  
    HyWCMK6b  
    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 *;*r 8[U}q  
    h'F=YF$o  
    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: U4B( #2'  
    1. 在FRED脚本编辑界面找到参考. 83q6Sv  
    2. 找到Matlab Automation Server Type Library #;nYg?d=  
    3. 将名字改为MLAPP yz8jw:d^-

    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。 G'A R`"F

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 9q[oa5INd  
    1. 创建Matlab服务器。 Dm<A ^u8  
    2. 移动探测面对于前一聚焦面的位置。  kPLxEwl  
    3. 在探测面追迹光线 <e</m)j  
    4. 在探测面计算照度 pIX`MlBdF  
    5. 使用PutWorkspaceData发送照度数据到Matlab e^D]EA ]%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b1?'gn~  
    7. 用Matlab画出照度数据 N<injx  
    8. 在Matlab计算照度平均值 )P|),S,;Z  
    9. 返回数据到FRED中 oM`0y@QCf
