    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。 *"cK_MH/o  
    So?.V4aD_  
    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: zzlqj){F  
    enableservice('AutomationServer', true) 6yDj1PI  
        enableservice('AutomationServer') s |40v@ M  
    (CUrFZT$  
    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 -Iq W@|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: !-G'8a|7  
    1. 在FRED脚本编辑界面找到参考. ZtzSG@f  
    2. 找到Matlab Automation Server Type Library )q.Z}_,)@  
        3. 将名字改为MLAPP ceiUpWMu,

         NxOiT#YH  
    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。 8]SJ=c"}Xf

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ? PIq/[tk  
    1. 创建Matlab服务器。 A%Ov.~&\G  
    2. 移动探测面对于前一聚焦面的位置。 }Iyr u3M][  
    3. 在探测面追迹光线 t1LIZ5JY  
    4. 在探测面计算照度 :eK(9o  
    5. 使用PutWorkspaceData发送照度数据到Matlab ioIOyj  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 M<Gr~RKmAn  
    7. 用Matlab画出照度数据 ~Onj| w7  
    8. 在Matlab计算照度平均值 Fe:M'.  
    9. 返回数据到FRED中 _'eG
