    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。 Y{S/A*X  
    g 08 `=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: . =+7H`A  
    enableservice('AutomationServer', true) O4#zsr:"  
    enableservice('AutomationServer') 2n7[Op  
    kOc'@;_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 -`gC?yff:

    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: tJn2:}-s  
    1. 在FRED脚本编辑界面找到参考. 9 o18VJR  
    2. 找到Matlab Automation Server Type Library Z*Y?"1ar  
    3. 将名字改为MLAPP ht-6_]+ME

    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。 T S.lFg:K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 4EELaP|%  
    1. 创建Matlab服务器。 S%4hv*_c  
    2. 移动探测面对于前一聚焦面的位置。 FStfGN  
    3. 在探测面追迹光线 `BvcI n4do  
    4. 在探测面计算照度 v{jl)?`~w  
    5. 使用PutWorkspaceData发送照度数据到Matlab HC0puLt_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;F:(5GBi  
    7. 用Matlab画出照度数据 N,O[pTwj  
    8. 在Matlab计算照度平均值 r({(;  
    9. 返回数据到FRED中 GphG/C (
