    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。 Fv<`AU  
    S;]*)i,v  
    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: ``E/m<r:$  
    enableservice('AutomationServer', true) s=42uKz  
    enableservice('AutomationServer') qY[xpm  
    } (!EuLL  
    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 IUtx!.]4

    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: VE8;sGaJ  
    1. 在FRED脚本编辑界面找到参考. p<:!)kt  
    2. 找到Matlab Automation Server Type Library "1, pHR-+R  
    3. 将名字改为MLAPP Qyy.IPTP

    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。 "+unS)M;Y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )aX,%yK  
    1. 创建Matlab服务器。 j!3 Gz  
    2. 移动探测面对于前一聚焦面的位置。 SB)5@ nmS  
    3. 在探测面追迹光线 |<O9Sb_  
    4. 在探测面计算照度 2YDM9`5xs\  
    5. 使用PutWorkspaceData发送照度数据到Matlab a5w:u5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )Y)pmjZaG  
    7. 用Matlab画出照度数据 tr7<]Hm:  
    8. 在Matlab计算照度平均值 $HJwb-I  
    9. 返回数据到FRED中 1T[et-
