    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。 QwhO /  
    epnZGz,A  
    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: %_Vz0 D! 7  
    enableservice('AutomationServer', true) \2/X$x<?X  
    enableservice('AutomationServer') n8EKTuy  
    6h/!,j0:t_  
    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 D/=05E%[81  
    P[ o"%NZ'  
    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,W@C  
    1. 在FRED脚本编辑界面找到参考. e2=}qE7  
    2. 找到Matlab Automation Server Type Library {O _X/y~  
    3. 将名字改为MLAPP k H65k (  
    -4QZ/*  
    co\?SgE35  
    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。 Mt4]\pMUb

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 15{^waR6  
    1. 创建Matlab服务器。 s&ox%L4  
    2. 移动探测面对于前一聚焦面的位置。 v>K|hH  
    3. 在探测面追迹光线 L?u {vX  
    4. 在探测面计算照度 |h $Gs2  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ia](CN*;6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 DH\Ox>b=  
    7. 用Matlab画出照度数据 ]rGd!"q  
    8. 在Matlab计算照度平均值 i-0 :Fs  
    9. 返回数据到FRED中 Q% aF~
