    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。 Xd!=1 ::  
    ,3qi]fFLMe  
    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: %($sj| _l  
    enableservice('AutomationServer', true) P"cc$lB~I  
    enableservice('AutomationServer') K)`, |q* \  
    % TyR8 %  
    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 cP`o?:

    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: LBk1Qw}-  
    1. 在FRED脚本编辑界面找到参考. P`v%< 9~  
    2. 找到Matlab Automation Server Type Library GE\@mu *pO  
    3. 将名字改为MLAPP 5lu620o

    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。 3gQQ,V..

    3. 在探测面追迹光线 N1jj\.nB  
    4. 在探测面计算照度 3+;]dqZ

    6. 使用PutFullMatrix发送标量场数据到Matlab中 L NmsvU  
    7. 用Matlab画出照度数据 cfyN)#9  
    8. 在Matlab计算照度平均值 DB-4S-2
