    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。 I*Dj@f`  
    qOy(dG g  
    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: 1ow,'FztPt  
    enableservice('AutomationServer', true) *j]Bo,AC  
    enableservice('AutomationServer') %La7);SeY  
    B*O/>=_  
    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 b j@R[!ss  
    N atC}k  
    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: W[DoQ @q  
    1. 在FRED脚本编辑界面找到参考. F*#!hWtb  
    2. 找到Matlab Automation Server Type Library } %?or_f/  
    3. 将名字改为MLAPP @OT$* Qh

    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。 =>c0NT

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,.( :b82$  
    1. 创建Matlab服务器。 v\8v'EDP  
    2. 移动探测面对于前一聚焦面的位置。 HLqN=vE6  
    3. 在探测面追迹光线 |-{e!&  
    4. 在探测面计算照度 qzvht4  
    5. 使用PutWorkspaceData发送照度数据到Matlab am3.Dt2\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xg, 9~f[  
    7. 用Matlab画出照度数据 Q`'cxx  
    8. 在Matlab计算照度平均值 Ih.)iTs~%  
    9. 返回数据到FRED中 ZDzG8E0Sq
