    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。 |xZDc6HDW  
    FH)bE#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: 7U:,:=  
    enableservice('AutomationServer', true) <4bv=++pS  
    enableservice('AutomationServer') K~<pD:s  
    %56pP"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 GsqR8n=  
    @I\Z2-J  
    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: L$zT`1Hy  
    1. 在FRED脚本编辑界面找到参考. _55T  
    2. 找到Matlab Automation Server Type Library =vT3SY  
    3. 将名字改为MLAPP '[-gK n

    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。 _Ta9rDSP]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: '97)c7E  
    1. 创建Matlab服务器。 po*s  
    2. 移动探测面对于前一聚焦面的位置。 L'6_~I  
    3. 在探测面追迹光线 j:"+/5rV8  
    4. 在探测面计算照度 |o~FKy1'z\  
    5. 使用PutWorkspaceData发送照度数据到Matlab (sS[F-2R7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [A|W0  
    7. 用Matlab画出照度数据 -kES]P?2  
    8. 在Matlab计算照度平均值 |4-c/@D.~  
    9. 返回数据到FRED中 eG|e1tK+
