    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。 Yv/T6z@  
    EdTR]}8  
    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: 045_0+r"@  
    enableservice('AutomationServer', true) ^N&@7s  
    enableservice('AutomationServer') DS|q(O=7~t  
    '\% Kd+k  
    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 O^~Z-; FA  
    ,92wW&2  
    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!C!  
    1. 在FRED脚本编辑界面找到参考. 6FkBb !ASk  
    2. 找到Matlab Automation Server Type Library \P;2s<6i\  
    3. 将名字改为MLAPP t Uk)S  
    ECk* H  
    n.7-$1  
    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。 -oT3`d3

    现在将脚本代码公布如下,此脚本执行如下几个步骤: `hf`lq^  
    1. 创建Matlab服务器。 `t#9 yN  
    2. 移动探测面对于前一聚焦面的位置。 rcz9\@M  
    3. 在探测面追迹光线 Wi@YJ  
    4. 在探测面计算照度 ?UV|m  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2QgD<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 im@QJ :  
    7. 用Matlab画出照度数据 9~{,Hj1xE  
    8. 在Matlab计算照度平均值 k`B S{,=  
    9. 返回数据到FRED中 1G8,Eah
