    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。 +?"N5%a%F  
    2.''Nt6|  
    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: "},0Cs  
    enableservice('AutomationServer', true) 9A|deETa-  
    enableservice('AutomationServer') 'Xj9sAB  
    yGGQ;!/  
    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 jUny&Alj

    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: <cC0l-=  
    1. 在FRED脚本编辑界面找到参考. l#40VHa?S  
    2. 找到Matlab Automation Server Type Library ahezDDR-.i  
    3. 将名字改为MLAPP w[`2t{^j  
    O>8|Lc  
    |Z\?nZ~  
    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。 >%qk2h>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -e#~CE-  
    1. 创建Matlab服务器。 :exgdm;N  
    2. 移动探测面对于前一聚焦面的位置。 ;ZnSWIF2  
    3. 在探测面追迹光线 %V40I{1  
    4. 在探测面计算照度 lr >:S  
    5. 使用PutWorkspaceData发送照度数据到Matlab SZ/}2_;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 k7o49Y(#  
    7. 用Matlab画出照度数据 )C?bb$  G  
    8. 在Matlab计算照度平均值 PwF 1Pr`r  
    9. 返回数据到FRED中 ~3]ZN'b\
