    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。 +e_NpC  
    4UD7!  
    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: tqyR~  
    enableservice('AutomationServer', true) s.z(1MB]  
    enableservice('AutomationServer') )G6{JL-I  
    Dp|y&x!  
    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 9:zW$Gt&  
    zs!,PQF(  
    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: R}lS@w1  
    1. 在FRED脚本编辑界面找到参考. ''P.~~ezr5  
    2. 找到Matlab Automation Server Type Library 'Ba Ba=  
    3. 将名字改为MLAPP e"HA.t[A  
    g[<K FVlG  
    ]pi"M 3f_  
    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。 F9(*MP|

    1. 创建Matlab服务器。 dH"wYMNL  
    2. 移动探测面对于前一聚焦面的位置。 SQ7Ws u>T@  
    3. 在探测面追迹光线 -[A4B)  
    4. 在探测面计算照度 %>^CD_[eO  
    5. 使用PutWorkspaceData发送照度数据到Matlab csP 5R3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vd`;(4i#X  
    7. 用Matlab画出照度数据 ${\iHg[vZ  
    8. 在Matlab计算照度平均值 :tclYX  
    9. 返回数据到FRED中 @-y.Y}k#$~
