    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。 ]Yx&  
    vCsJnKqK  
    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: }CB9H$FkCY  
    enableservice('AutomationServer', true) =q?sB]n  
    enableservice('AutomationServer') tde&w=ec  
    r>Cv@4/j  
    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 M:d} P

    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: 9MUg/  
    1. 在FRED脚本编辑界面找到参考. Bl/Z _@  
    2. 找到Matlab Automation Server Type Library MVOWJaT(Aq  
    3. 将名字改为MLAPP ^Q5advxuq

    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。 NZ:KJ8ea"

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )POU58$  
    1. 创建Matlab服务器。 `C>De4nT@  
    2. 移动探测面对于前一聚焦面的位置。  re@;6o  
    3. 在探测面追迹光线 R-OQ(]<*  
    4. 在探测面计算照度 ;kR+jC(  
    5. 使用PutWorkspaceData发送照度数据到Matlab cs7K^D;.V  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4v;KtD;M  
    7. 用Matlab画出照度数据 T/iZ"\(~w  
    8. 在Matlab计算照度平均值 k4`(7Z  
    9. 返回数据到FRED中 "T1A$DKw+R
