    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。 "MU)8$d  
    vC_O! 2E  
    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: u,),kj<  
    enableservice('AutomationServer', true) VDC"tSQ  
    enableservice('AutomationServer') n8 e4`-cY  
    )kK" 1\m  
    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 r!HB""w  
    O:Ob{k  
    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: ["XS|"DM  
    1. 在FRED脚本编辑界面找到参考. ff<ad l-  
    2. 找到Matlab Automation Server Type Library @d_;p<\l  
    3. 将名字改为MLAPP p="K4E8~H  
    6HxZS+], c  
    4&'_~qU  
    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。 HK!Vd_&9,

    3. 在探测面追迹光线 ffE&=eh)  
    4. 在探测面计算照度 .47tj`L   
    5. 使用PutWorkspaceData发送照度数据到Matlab SWM6+i p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e \ rb  
    7. 用Matlab画出照度数据 jj*e.t:F  
    8. 在Matlab计算照度平均值 h2#S ?  
    9. 返回数据到FRED中 TLiA>`r=
