    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。 I6W`yh`I)  
    sjr,)|#[  
    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: &riGzU]  
    enableservice('AutomationServer', true) 1cLtTE  
    enableservice('AutomationServer') Z<-_Y]4j  
    9=%zdz2_S  
    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 ,#A(I#wL~  
    W)In.?>]W  
    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: G*fo9eu5$  
    1. 在FRED脚本编辑界面找到参考. QJGGce  
    2. 找到Matlab Automation Server Type Library WQK<z!W5  
    3. 将名字改为MLAPP z8Q!~NN-K  
    Km` SR^&\  
    FzT.9Vz7  
    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。 ~t`^|cr|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: .+9hm|  
    1. 创建Matlab服务器。 >lQo _p(;  
    2. 移动探测面对于前一聚焦面的位置。 SB_Tzp  
    3. 在探测面追迹光线 tIsWPt]Y  
    4. 在探测面计算照度 `8:)? 0Ez  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?"6Zf LRi  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 L"bOc'GfQ  
    7. 用Matlab画出照度数据 06&J!,p :  
    8. 在Matlab计算照度平均值 Q`ua9oIJ=  
    9. 返回数据到FRED中 I"07x'Ahq3
