    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。 v. Xoq  
    +:>JZ$  
    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: Gg9VS&VI  
    enableservice('AutomationServer', true) a(@p0YpKT  
    enableservice('AutomationServer') <8rgtu!VU  
    !.3R~0b  
    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 T3Frc ]6,4  
    [6; N3?+  
    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: zb5N,!%r  
    1. 在FRED脚本编辑界面找到参考. -]Q(~'a  
    2. 找到Matlab Automation Server Type Library n$XdSh/   
    3. 将名字改为MLAPP IX<r5!

    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。 {[2tG U9

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )?w&oIj5  
    1. 创建Matlab服务器。 &:V@2_6"

    3. 在探测面追迹光线 T&r +G!2  
    4. 在探测面计算照度 &P 8!]:  
    5. 使用PutWorkspaceData发送照度数据到Matlab hCzjC|EO~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 W.A1m4l58R  
    7. 用Matlab画出照度数据 E@w[&#  
    8. 在Matlab计算照度平均值 LBiowd[  
    9. 返回数据到FRED中 ^ <qrM
