    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。 +j`5F3@  
    e#L8X {f  
    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: q#Z@+(^  
    enableservice('AutomationServer', true) !N\@'F!  
    enableservice('AutomationServer') 7 S#J>*  
    *v jmy/3  
    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 55nlg>j  
    53;}Nt#R  
    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: |"X*@s\'  
    1. 在FRED脚本编辑界面找到参考. U3ADsdn  
    2. 找到Matlab Automation Server Type Library uB]7G0g:  
    3. 将名字改为MLAPP | C;=-|

    G6q }o)[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。 Zw 26

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6"L cJ%o  
    1. 创建Matlab服务器。 =1FRFZI!j  
    2. 移动探测面对于前一聚焦面的位置。 b(eNmu  
    3. 在探测面追迹光线 )0.kv2o.  
    4. 在探测面计算照度 U8s2|G;K  
    5. 使用PutWorkspaceData发送照度数据到Matlab $B 2J T9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 fIx+IL s  
    7. 用Matlab画出照度数据 9N#_( uwt  
    8. 在Matlab计算照度平均值 fa jGZyd0:  
    9. 返回数据到FRED中 BM%e0n7
