    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。 E2>im>p  
    DY$yiOH9  
    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: F?!FD>L{`  
    enableservice('AutomationServer', true) S|l&fb n  
    enableservice('AutomationServer') YavfjS:2  
    ].LJt['%8  
    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 D*|( p6v1&  
    kBrvl^D{5  
    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: kJ/+IGV^v  
    1. 在FRED脚本编辑界面找到参考. #N; $  
    2. 找到Matlab Automation Server Type Library .=?Sz*3

    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。 rU],J!LF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: X)I/%{  
    1. 创建Matlab服务器。 fv:L\N1u  
    2. 移动探测面对于前一聚焦面的位置。 ^GN5vT+:'  
    3. 在探测面追迹光线 wyp{KIV  
    4. 在探测面计算照度 `$H7KIG  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6KVV z/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b7Yq_%+  
    7. 用Matlab画出照度数据 ldP3n:7FS  
    8. 在Matlab计算照度平均值 "pYe-_"@  
    9. 返回数据到FRED中 RTA%hCr!
