    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。 *9tRh Rc  
    &vN^ *:Q  
    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:  6h?)x  
    enableservice('AutomationServer', true) <lTLz$QE  
    enableservice('AutomationServer') IsiBn(1Z  
    X.eocy  
    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 Y|cj&<o  
    L\xR<m<,  
    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: B{!*OC{l  
    1. 在FRED脚本编辑界面找到参考. >E9 k5  
    2. 找到Matlab Automation Server Type Library e[Jh7r>'  
    3. 将名字改为MLAPP Xx1eSX

    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。 3jjV bm

    1. 创建Matlab服务器。 _b9>ZF~  
    2. 移动探测面对于前一聚焦面的位置。 b<j*;n.  
    3. 在探测面追迹光线 PO*0jO;%  
    4. 在探测面计算照度 sp6A* mwl  
    5. 使用PutWorkspaceData发送照度数据到Matlab <&l@ ):a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s[#_sR`y  
    7. 用Matlab画出照度数据 DFp">1@`PR  
    8. 在Matlab计算照度平均值 v+C%t!dx
