    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。 8`=?_zF  
    <}a?<):S  
    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: O"m7r ds  
    enableservice('AutomationServer', true) 'uPAG;)m  
        enableservice('AutomationServer') PK*Wu<<  
    q*!R4yE;C  
    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 J8|MK.oD  
    _0H oJ  
    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: \j8vf0c5b  
    1. 在FRED脚本编辑界面找到参考. _k84#E0  
    2. 找到Matlab Automation Server Type Library +ikSa8)*i  
        3. 将名字改为MLAPP ?HEqv$n  
         $ {yc t  
         fHt\KP  
    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。 >7U/TVd&

    3. 在探测面追迹光线 X+vKY  
    4. 在探测面计算照度 U ?[ (  
    5. 使用PutWorkspaceData发送照度数据到Matlab W/'1ftn?D  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 *_V+K  
    7. 用Matlab画出照度数据 ]ua3I}_B6v
