    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。 0MwG}|RC  
    =?meO0]y  
    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: z1Bj_u{  
    enableservice('AutomationServer', true) Gl?P.BCW.&  
    enableservice('AutomationServer') X@6zI-Y %  
    :N^@a-  
    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 ]I{qp~^#n

    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: Ck ~V5  
    1. 在FRED脚本编辑界面找到参考. uB5h9&57  
    2. 找到Matlab Automation Server Type Library .\z|Fr  
    3. 将名字改为MLAPP =$"zqa.B6  
    K$MJ#Zx^  
    lH#@^i|G  
    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。 /3)YWFZZc

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <.PPs:{8#

    2. 移动探测面对于前一聚焦面的位置。 09}f\/  
    3. 在探测面追迹光线 l|@/?GaH  
    4. 在探测面计算照度 K#9(|2 J%  
    5. 使用PutWorkspaceData发送照度数据到Matlab `-72>F;T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &=s|  
    7. 用Matlab画出照度数据 E1Ru)k{B  
    8. 在Matlab计算照度平均值 &%f]-=~  
    9. 返回数据到FRED中 4b3F9
