    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。 'L,rJ =M3  
    3EFk] X  
    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: gk&?h7P"<  
    enableservice('AutomationServer', true) x6,RW],FGR  
    enableservice('AutomationServer') UJZa1p@L  
    ka'MF;!rc  
    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 ]oY~8HW

    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: =19]a  
    1. 在FRED脚本编辑界面找到参考. /L~*FQQK>  
    2. 找到Matlab Automation Server Type Library O$$N{  
    3. 将名字改为MLAPP %ry>p(-pC(

    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。 H5 -I}z

    3. 在探测面追迹光线 <s:Xj  
    4. 在探测面计算照度 4[#.N 3Y4*

    6. 使用PutFullMatrix发送标量场数据到Matlab中 lC2xl(#!  
    7. 用Matlab画出照度数据 D^u{zZy@e  
    8. 在Matlab计算照度平均值 ^KlOD_GN|
