    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。 Q~b_dx{m  
    Stt* 1gT  
    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: <0>[c<{V<  
    enableservice('AutomationServer', true) t +J)dr  
    enableservice('AutomationServer') `[&v  
    juXC?2c  
    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 C?S~L5a#oC

    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: E::<; 9  
    1. 在FRED脚本编辑界面找到参考. 8| Sba<d  
    2. 找到Matlab Automation Server Type Library &%}bRPUl  
    3. 将名字改为MLAPP dhs#D:/{9  
    AsD1-$  
    P$Ax c/H  
    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。 EL"4E',

    2. 移动探测面对于前一聚焦面的位置。 Na-q%ru  
    3. 在探测面追迹光线 )S#j.8P'B  
    4. 在探测面计算照度 yTP[,bM  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2=Jmi?k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9W$m D w6f  
    7. 用Matlab画出照度数据 6OMb`A@/2  
    8. 在Matlab计算照度平均值 -}N Ab^d
