    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。 A}w/OA97RO  
    8XaQAy%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: E`J@h l$N  
    enableservice('AutomationServer', true) $Kd>:f=A  
    enableservice('AutomationServer') 'fW-Y!k%  
    ^f@=:eWI  
    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 Bp{Ri_&A  
    tX[WH\(xI  
    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: d_ CT $  
    1. 在FRED脚本编辑界面找到参考. d'ifLQ\  
    2. 找到Matlab Automation Server Type Library R-14=|7a-  
    3. 将名字改为MLAPP &j6erwaT

    1mJ Hued=6  
    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。 d5-qZ{W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T{'RV0%   
    1. 创建Matlab服务器。 ?cZlN !  
    2. 移动探测面对于前一聚焦面的位置。 @nf`Gw ;  
    3. 在探测面追迹光线 DwF hK*  
    4. 在探测面计算照度 qP;OaM CX  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2qp#N%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JS77M-Ac  
    7. 用Matlab画出照度数据 W l4%GB  
    8. 在Matlab计算照度平均值 h];I{crh  
    9. 返回数据到FRED中 8Y?;x}
