    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。 _P.+[RS@  
    X(kyu,w  
    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: 9{\e E]0  
    enableservice('AutomationServer', true) 2i`N26On  
    enableservice('AutomationServer') 4^(u6tX5|+  
    I `:nb  
    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 TcA+ov>TD  
    l/0TNOA  
    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: }6b=2Z}  
    1. 在FRED脚本编辑界面找到参考. P3C|DO4  
    2. 找到Matlab Automation Server Type Library Y}%=:Yt  
    3. 将名字改为MLAPP cN_e0;*Ua

    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。 #!0le:_

    2. 移动探测面对于前一聚焦面的位置。 f@&C \  
    3. 在探测面追迹光线 hyv*+FV;  
    4. 在探测面计算照度 9^l_\:4  
    5. 使用PutWorkspaceData发送照度数据到Matlab pv8"E?9,k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ag QR"Nu6  
    7. 用Matlab画出照度数据 ;Q>(%"z};
