    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。  g_q<ze  
    @Y-TOCadT  
    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: mQr0sI,o]  
    enableservice('AutomationServer', true) fu]N""~  
        enableservice('AutomationServer') >qh?L#Fk  
    Hg+ F^2<y  
    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 }l;Lxb2`  
    .Dw,"VHP  
    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: K)N0,Qwu  
    1. 在FRED脚本编辑界面找到参考. u #~ ;&D*q  
    2. 找到Matlab Automation Server Type Library wC` R>)  
        3. 将名字改为MLAPP &&7r+.Y  
         O3qM1-k}S  
         4l @)K9F  
    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。 |/T43ADW

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n:4uA`Vg  
    1. 创建Matlab服务器。 v(O=IUa  
    2. 移动探测面对于前一聚焦面的位置。 8l>CR#%@C  
    3. 在探测面追迹光线 4["&O=:d  
    4. 在探测面计算照度 Vmi{X b]<  
    5. 使用PutWorkspaceData发送照度数据到Matlab X?o( b/F -  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 OYmi?y\  
    7. 用Matlab画出照度数据 VQxpN 1  
    8. 在Matlab计算照度平均值 Jpj!rXTX*  
    9. 返回数据到FRED中  +sZUJ
