    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。 X'O3)Yg  
    ?v6xa Vg:  
    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: SDZ/rC!C  
    enableservice('AutomationServer', true) ,XR1N$LN8_  
        enableservice('AutomationServer') f`T#=6C4|  
    .|!Kv+yD  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 &S/KR$^ %  
    h^cM#L^B  
    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: "HlT-0F  
    1. 在FRED脚本编辑界面找到参考. ]5wc8Kh"  
    2. 找到Matlab Automation Server Type Library $)6y:t"  
        3. 将名字改为MLAPP usU5q>1

         x:GuqE  
    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。 4/cUd=>Z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: z]K:Amp;Z  
    1. 创建Matlab服务器。 'V/+v#V+>  
    2. 移动探测面对于前一聚焦面的位置。 )ui]vS:>  
    3. 在探测面追迹光线 `-IX"rf  
    4. 在探测面计算照度 (*F/^4p!$  
    5. 使用PutWorkspaceData发送照度数据到Matlab mSr(PIH{\  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 l%L..WCT]  
    7. 用Matlab画出照度数据 :A"GO c,  
    8. 在Matlab计算照度平均值 ^i:%0"[*^i  
    9. 返回数据到FRED中 jhg0H2C8
