    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。 RPLr7Lb  
    sX@e1*YE_  
    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: M`"2;  
    enableservice('AutomationServer', true) 15SIZ:Q  
    enableservice('AutomationServer') S~m* t i(  
    hf%W grO.  
    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 @^`-VF  
    ]Q^oc  
    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: 1f~_# EIC  
    1. 在FRED脚本编辑界面找到参考. QAX+oy  
    2. 找到Matlab Automation Server Type Library X2o5Hc)l<  
    3. 将名字改为MLAPP {9P<G]Z  
    6#dx%TC  
    NbgP,-  
    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。 !n !~Bw

    现在将脚本代码公布如下,此脚本执行如下几个步骤: LZ^sc  
    1. 创建Matlab服务器。 bv|v9_i  
    2. 移动探测面对于前一聚焦面的位置。 _gU [FUBtJ  
    3. 在探测面追迹光线 783a Z8  
    4. 在探测面计算照度 *r(iegO$  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]Y, 7 X  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w}7`Vas9  
    7. 用Matlab画出照度数据 NH|v`rO  
    8. 在Matlab计算照度平均值 >R.~'A/$F  
    9. 返回数据到FRED中 Kz'W |
