    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。 &liFUP?   
    AjO{c=d  
    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: ht+wi5b  
    enableservice('AutomationServer', true) (KvN#d 1\  
    enableservice('AutomationServer') c>r~pY~$  
    VY|U B7,C  
    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 A??a:8id^  
    )\W}&9 >  
    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: _S* QIbO  
    1. 在FRED脚本编辑界面找到参考. )$pqe|,  
    2. 找到Matlab Automation Server Type Library p2O[r  
    3. 将名字改为MLAPP ^4[QX -_2

    U`{ M1@$  
    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。 E3x<o<v

    现在将脚本代码公布如下,此脚本执行如下几个步骤: R$it`0D4o  
    1. 创建Matlab服务器。 ePSD#kY5  
    2. 移动探测面对于前一聚焦面的位置。 v9gaRqi8  
    3. 在探测面追迹光线 @te}Asv  
    4. 在探测面计算照度 ,&@FToR  
    5. 使用PutWorkspaceData发送照度数据到Matlab y#O/Xw  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 M%!j\}2A  
    7. 用Matlab画出照度数据 20A:,pMb  
    8. 在Matlab计算照度平均值 {=Py|N \\t  
    9. 返回数据到FRED中 2@&"*1(Xu
