    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。 =o HJ_  
    om/gk4S2  
    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: U>I#f  
    enableservice('AutomationServer', true) i$NnHj|  
    enableservice('AutomationServer') tx.YW9xD  
    |6;.C1\,  
    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 Q,DumOq  
    $L`7J$'^  
    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: /3c1{%B\  
    1. 在FRED脚本编辑界面找到参考. Jq; }q63:  
    2. 找到Matlab Automation Server Type Library f~U|flL^  
    3. 将名字改为MLAPP B}!n6j`

    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。 nrxN_0 R%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: S_WY91r  
    1. 创建Matlab服务器。 \m\.+q]  
    2. 移动探测面对于前一聚焦面的位置。 Df4n9m}E  
    3. 在探测面追迹光线 7u}r^+6_o  
    4. 在探测面计算照度 6Q>w\@lF  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]pGr'T~Gj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &\(YmY  
    7. 用Matlab画出照度数据 0- #ct1-  
    8. 在Matlab计算照度平均值 tN0>5'/  
    9. 返回数据到FRED中 !eO?75/
