    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。 tYx>?~   
    %]o/p_<  
    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: Qa"4^s  
    enableservice('AutomationServer', true) )4n]n:FjN  
    enableservice('AutomationServer') `~ h8D9G  
    pbG v\S F  
    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 :DFtH13qO  
    ,v#3A7"yW  
    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: e4;h*IQK  
    1. 在FRED脚本编辑界面找到参考. P8 R^46  
    2. 找到Matlab Automation Server Type Library ozl>Au  
    3. 将名字改为MLAPP !4$-.L)#

    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。 +ux`}L(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: B8>@q!G8P  
    1. 创建Matlab服务器。 J5}?<Dd:  
    2. 移动探测面对于前一聚焦面的位置。 pAyUQe;X#  
    3. 在探测面追迹光线 }*7Gq  
    4. 在探测面计算照度 R  xc  
    5. 使用PutWorkspaceData发送照度数据到Matlab jm[f|4\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Pxgal4{6  
    7. 用Matlab画出照度数据 0<nW nD,z  
    8. 在Matlab计算照度平均值 c&"1Z/tR  
    9. 返回数据到FRED中 g ~%IA.$c
