    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。 CC#;c1t  
    bFe+m1Q_  
    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: ,lZB96r0  
    enableservice('AutomationServer', true) j@YU|-\qh  
    enableservice('AutomationServer') yE}}c{hSn  
     GB$;n?  
    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 uV!^,,~  
    ;\f gF@  
    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: C:PMewn  
    1. 在FRED脚本编辑界面找到参考. ]IoUwgpI)  
    2. 找到Matlab Automation Server Type Library q Y#n'&  
    3. 将名字改为MLAPP ?b(=1S\E'^

    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。 xuqv6b.

    现在将脚本代码公布如下,此脚本执行如下几个步骤: D#3\y*-y?  
    1. 创建Matlab服务器。 q WQ/ 'M  
    2. 移动探测面对于前一聚焦面的位置。 Q_[ 3`j l  
    3. 在探测面追迹光线 3AU;>D^5  
    4. 在探测面计算照度 7=;R& mqC  
    5. 使用PutWorkspaceData发送照度数据到Matlab V5UF3'3;}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _f$^%?^  
    7. 用Matlab画出照度数据 <StN%2WQ1  
    8. 在Matlab计算照度平均值 <1uZa  
    9. 返回数据到FRED中 r"P|dlV-
