    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。 G>0)I  
    n?Zf/T  
    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: +-P<CCvWz  
    enableservice('AutomationServer', true) 8t\}c6/3"  
    enableservice('AutomationServer') raHVkE{<  
    B^m!t7/,  
    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 f9F2U )  
    X <FOn7qf  
    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: YZ\@)D;  
    1. 在FRED脚本编辑界面找到参考. e>!E=J)j  
    2. 找到Matlab Automation Server Type Library ~o Fh>9u  
    3. 将名字改为MLAPP H9E(\)@

    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。 j"6:A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ol#yjrv  
    1. 创建Matlab服务器。 ]|y}\7Aa  
    2. 移动探测面对于前一聚焦面的位置。 )-#i8?y3C  
    3. 在探测面追迹光线 @Wz%KdXA  
    4. 在探测面计算照度 QES^^PQe:  
    5. 使用PutWorkspaceData发送照度数据到Matlab U1kh-8  :  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 lG 8dI\`  
    7. 用Matlab画出照度数据 m2ox8(sd  
    8. 在Matlab计算照度平均值 gi 5XP]z  
    9. 返回数据到FRED中 oX*b<d{\N
