    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。 ,{"K^  
    e=jtF"&  
    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<r*EY  
    enableservice('AutomationServer', true) %PR,TWe  
        enableservice('AutomationServer') ?<0'h{zNy  
    m=pH G  
    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 mT j  
    ]t17= Lr?  
    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: DB jUHirK  
    1. 在FRED脚本编辑界面找到参考. i)'u!V  
    2. 找到Matlab Automation Server Type Library b5|l8<\  
        3. 将名字改为MLAPP X2~KNw  
         f~jd N~  
         x)q$.u+  
    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。 guy!/zQ>A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: nu|?F\o!  
    1. 创建Matlab服务器。 _ -ec(w~/  
    2. 移动探测面对于前一聚焦面的位置。 >X>]QMfh  
    3. 在探测面追迹光线 }ZwnG=7T?  
    4. 在探测面计算照度 (Zy=e?E,  
    5. 使用PutWorkspaceData发送照度数据到Matlab S[rfcL"  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 lm'.G99{  
    7. 用Matlab画出照度数据 7` XECIh  
    8. 在Matlab计算照度平均值 hB:+_[=Kj.  
    9. 返回数据到FRED中 e [F33%
