    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。 %OJ"@6A  
    ]FNe&o1zX  
    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: c( _R xLJ  
    enableservice('AutomationServer', true) ffW-R)U|3  
    enableservice('AutomationServer') V= g u'~  
    g& ou[_A  
    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 63`5A3rii

    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: U(+%iD60i  
    1. 在FRED脚本编辑界面找到参考. '2qbIYanh  
    2. 找到Matlab Automation Server Type Library r}:D g fn  
    3. 将名字改为MLAPP ! FVD_8

    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。 ep6V2R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: wwNkJ+  
    1. 创建Matlab服务器。 !5qV}5  
    2. 移动探测面对于前一聚焦面的位置。 O]XgA0]  
    3. 在探测面追迹光线 tUksIUYD\  
    4. 在探测面计算照度 s"`Oj5  
    5. 使用PutWorkspaceData发送照度数据到Matlab _'|C-j`u$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C1#f/o->  
    7. 用Matlab画出照度数据 DaBy<pGb?  
    8. 在Matlab计算照度平均值 4d_Az'7`4  
    9. 返回数据到FRED中 HXN. ,[
