    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。 'l~6ErBSg  
    #/|75 4]]  
    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: PocYFhWQ`  
    enableservice('AutomationServer', true) ~3gru>qI&  
    enableservice('AutomationServer') &-M]xo ^  
    9M_(He -  
    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 |g%mP1O  
    Zmf'{tT5  
    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: EM@ ;3.IO  
    1. 在FRED脚本编辑界面找到参考. '0:i<`qv#g  
    2. 找到Matlab Automation Server Type Library Ow3P-UzU3  
    3. 将名字改为MLAPP #Z\ O}<

    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。 k@V#HC{t

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {^5?)/<  
    1. 创建Matlab服务器。 q@n^ZzTx  
    2. 移动探测面对于前一聚焦面的位置。 mffIf1f  
    3. 在探测面追迹光线 -I":Z2.fR  
    4. 在探测面计算照度 ahJ1n<  
    5. 使用PutWorkspaceData发送照度数据到Matlab Tv5g`/e=Ej  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3$VxRz)  
    7. 用Matlab画出照度数据 ;gMgj$mI  
    8. 在Matlab计算照度平均值 ?7jg(`Yh  
    9. 返回数据到FRED中 H2;X
