    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。 N8df8=.kw  
    G 01ON0  
    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: ,eS)e+yzc2  
    enableservice('AutomationServer', true) d&>^&>?$zh  
    enableservice('AutomationServer') ^S; -fYW2  
    1< ?4\?j  
    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 ~a2}(]  
    m9;SrCN_  
    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: .T`%tJ-Em  
    1. 在FRED脚本编辑界面找到参考. E!F^H^~$8  
    2. 找到Matlab Automation Server Type Library #KvlYZ+1  
    3. 将名字改为MLAPP :g/tZd$G5

    1|=A*T-<M  
    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。 1|:KQl2q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 2~[juWbz  
    1. 创建Matlab服务器。 uQzXfOq  
    2. 移动探测面对于前一聚焦面的位置。 `WS&rmq&'  
    3. 在探测面追迹光线 [V`r^  
    4. 在探测面计算照度 * v#o  
    5. 使用PutWorkspaceData发送照度数据到Matlab \Oo Wo  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 yf,z$CR  
    7. 用Matlab画出照度数据 cWm$;`Q#\  
    8. 在Matlab计算照度平均值 P$,Ke<  
    9. 返回数据到FRED中 vP,n(reM
