    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。 0o"aSCq8t  
    ^9:`D@Z+  
    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: ao"2kqa)r  
    enableservice('AutomationServer', true) )iQ^HZ  
    enableservice('AutomationServer') 3ie k >'T  
    !Yv_V]u=  
    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 uVCH<6Cp  
    oV0T   
    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: ]i$0s  
    1. 在FRED脚本编辑界面找到参考. 4&sf{tI  
    2. 找到Matlab Automation Server Type Library ;=jF9mV.  
    3. 将名字改为MLAPP HyVV,q^E  
    Xt<1b  
    2&>t,;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。 Y~8 5Z0l

    现在将脚本代码公布如下,此脚本执行如下几个步骤: j2<+[h-  
    1. 创建Matlab服务器。 TZ5TkE;1  
    2. 移动探测面对于前一聚焦面的位置。 ZBK0`7#&EH  
    3. 在探测面追迹光线 Cl<!S`  
    4. 在探测面计算照度 W Su6chz)  
    5. 使用PutWorkspaceData发送照度数据到Matlab lAP k/G  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C$TU TS  
    7. 用Matlab画出照度数据 HS/.H,X  
    8. 在Matlab计算照度平均值 uBx\xeI  
    9. 返回数据到FRED中 y>aO90wJ
