    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。 @krh<T6|  
    @@QB,VS;{<  
    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: LV6BSQyQ  
    enableservice('AutomationServer', true) _enS_R  
    enableservice('AutomationServer') -nL!#R{e  
    [a2Q ^ab  
    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 ySP%i6!au

    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: _]"uq/UWp  
    1. 在FRED脚本编辑界面找到参考. c_Fz?R+f?K  
    2. 找到Matlab Automation Server Type Library *vS)aRK  
    3. 将名字改为MLAPP j3$\+<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。 loByT p ^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8HxtmFqG  
    1. 创建Matlab服务器。 ^a #  
    2. 移动探测面对于前一聚焦面的位置。 BqG7E t  
    3. 在探测面追迹光线 ^3 6oqe{  
    4. 在探测面计算照度 ;>jLRx<KC  
    5. 使用PutWorkspaceData发送照度数据到Matlab +h?Rb3=S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 %&\DCAFk  
    7. 用Matlab画出照度数据 L`@)*x)~R  
    8. 在Matlab计算照度平均值 dxk~  
    9. 返回数据到FRED中 i^_?C5
