    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。 8uCd|dJ  
    q F}5mUcZ4  
    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: Mzb_o2^(  
    enableservice('AutomationServer', true) ZJw9 2Sb  
    enableservice('AutomationServer') <{cPa\  
    8YYY *>  
    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 a(}jn|

    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: Y,)9{T  
    1. 在FRED脚本编辑界面找到参考. ";>D0h^D  
    2. 找到Matlab Automation Server Type Library V=S`%1dLN  
    3. 将名字改为MLAPP NT8%{>F`

    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。 X;}_[ =-

    1. 创建Matlab服务器。 [s7I.rdGzz  
    2. 移动探测面对于前一聚焦面的位置。 ? X:RrZ:/

    4. 在探测面计算照度 3K#e]zoI  
    5. 使用PutWorkspaceData发送照度数据到Matlab 1,pg:=N9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 cBm3|@7  
    7. 用Matlab画出照度数据 m:"2I&0)WM
