    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。 %$+bO/f  
    4{ED~w|  
    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: Q.l3F3;  
    enableservice('AutomationServer', true) w+{ o^ O  
    enableservice('AutomationServer') xyi4U(;  
    '.t{\  
    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 +)*oPSQ5

    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: 7k#0EhN1>  
    1. 在FRED脚本编辑界面找到参考. =O~Y6|  
    2. 找到Matlab Automation Server Type Library A7GWU{i  
    3. 将名字改为MLAPP 3 E!F8GZ

    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。 ?p &Xf>K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Ak,T{;rD  
    1. 创建Matlab服务器。 &bCk`]j:

    3. 在探测面追迹光线 X->` ~-aj  
    4. 在探测面计算照度 9&OhCrxW-  
    5. 使用PutWorkspaceData发送照度数据到Matlab [LKzH!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d5lD!  
    7. 用Matlab画出照度数据 LOe l6Ui  
    8. 在Matlab计算照度平均值 r<_qU3Eaj  
    9. 返回数据到FRED中 lQ?_1H~4=
