    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。 >5Lexj  
    < y>:B}9'  
    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: g:gB`8w?  
    enableservice('AutomationServer', true) "l,UOv c  
    enableservice('AutomationServer') g-@h>$< 1  
    J_ J+cRwq  
    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 iZ; TYcT

    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: @ yxt($G  
    1. 在FRED脚本编辑界面找到参考. Ze ? g  
    2. 找到Matlab Automation Server Type Library ~ FUa: KYD  
    3. 将名字改为MLAPP K t `

    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。 2p:r`THvS5

    1. 创建Matlab服务器。 EOVZGZF  
    2. 移动探测面对于前一聚焦面的位置。 r4eUZ .8R  
    3. 在探测面追迹光线 9?`RR/w  
    4. 在探测面计算照度 qm(1:iK,0  
    5. 使用PutWorkspaceData发送照度数据到Matlab rsF:4G"%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i_U}{|j  
    7. 用Matlab画出照度数据 nNn56&N]  
    8. 在Matlab计算照度平均值 (0jr;jv  
    9. 返回数据到FRED中 Vxh.<b6&'
