    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。 f?16%Rk<  
    7&]|c?([4  
    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: J5<1 6}*  
    enableservice('AutomationServer', true) dd +lQJ c  
    enableservice('AutomationServer') B o%Sl  
    /m^G 99N  
    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 >b:5&s\9

    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: *<"{(sAvk  
    1. 在FRED脚本编辑界面找到参考. eZhF<<Y  
    2. 找到Matlab Automation Server Type Library Qs#;sy W@~  
    3. 将名字改为MLAPP i]@k'2N

    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。 v:w^$]4

    1. 创建Matlab服务器。 >@-. rkd(  
    2. 移动探测面对于前一聚焦面的位置。 ,iZKw8]f  
    3. 在探测面追迹光线 XJwgh y?(  
    4. 在探测面计算照度 #i*PwgC%_  
    5. 使用PutWorkspaceData发送照度数据到Matlab q['3M<q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <y7Hy&&y-  
    7. 用Matlab画出照度数据 ,K30.E  
    8. 在Matlab计算照度平均值 4v{Ye,2
