    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。 Vlf=gP  
    Qt~QJJN?oF  
    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: GV"X) tGo  
    enableservice('AutomationServer', true) te*|>NRS  
    enableservice('AutomationServer') + lNAog  
    !l7D1i~  
    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 d%(4s~y  
    P.t0o~hoK;  
    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: vNn$dc  
    1. 在FRED脚本编辑界面找到参考. k@Q>(`  
    2. 找到Matlab Automation Server Type Library C4h4W3w  
    3. 将名字改为MLAPP M&h`uO/[  
    9^zA(  
    O={ ?c1i:  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 M~O$ ,dof  
    @&F\M}

    )zMsKfQ  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~]l T>|X  
    1. 创建Matlab服务器。 D&]dlY@*  
    2. 移动探测面对于前一聚焦面的位置。 }~bx==SF6!  
    3. 在探测面追迹光线 RHj<t");  
    4. 在探测面计算照度 RLE6=#4  
    5. 使用PutWorkspaceData发送照度数据到Matlab OGGuVY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 CW . O"_  
    7. 用Matlab画出照度数据 hAvX{]  
    8. 在Matlab计算照度平均值 k0>]7t$L  
    9. 返回数据到FRED中 wQR0R~|M
