    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。 B4b UcYk  
    -&&mkK B!  
    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: ua{eri[  
    enableservice('AutomationServer', true) \KEL.}B9E  
    enableservice('AutomationServer') X[|>r@Aa!  
    *D'V W{  
    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 FUH1Z+9  
    ILQg@J l  
    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#AB0-f  
    1. 在FRED脚本编辑界面找到参考. H1w;Wb1se  
    2. 找到Matlab Automation Server Type Library aCMcu\rd  
    3. 将名字改为MLAPP Q.N^1?(>k  
    Y8d%L;b[D  
    Q=dR[t>^  
    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。 u66w('2

    f ZISwr  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: W=DQ6.   
    1. 创建Matlab服务器。 BYGLYT;Z  
    2. 移动探测面对于前一聚焦面的位置。 iZ58;`  
    3. 在探测面追迹光线 w"D"9 G  
    4. 在探测面计算照度 IL~yJx_11  
    5. 使用PutWorkspaceData发送照度数据到Matlab YziQU_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 GY!&H"%  
    7. 用Matlab画出照度数据 `*slQ }i  
    8. 在Matlab计算照度平均值 X@cV']#V  
    9. 返回数据到FRED中 mF_/Rhu
