    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。 b}Hl$V(uD  
    &M3ES}6  
    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: JV]u(PL  
    enableservice('AutomationServer', true) "R2t&X[9  
    enableservice('AutomationServer') q X%vRf0  
    v V6Lp  
    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 C7 ]DJn

    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: >[H&k8\7n  
    1. 在FRED脚本编辑界面找到参考. FL#g9U>  
    2. 找到Matlab Automation Server Type Library 2@R8P~^W  
    3. 将名字改为MLAPP leES YSY:  
    k'ZUBTRq!  
    '`]n_$f'  
    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。 grCO-S|j^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ..q63dr  
    1. 创建Matlab服务器。 cF_;hD|YZ  
    2. 移动探测面对于前一聚焦面的位置。 :Dk@?o@2;C  
    3. 在探测面追迹光线 88#qu.  
    4. 在探测面计算照度 uojh%@.4  
    5. 使用PutWorkspaceData发送照度数据到Matlab LGo2^Xx  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q\27\2  
    7. 用Matlab画出照度数据 d2A wvP  
    8. 在Matlab计算照度平均值 S?Bc~y  
    9. 返回数据到FRED中 %R5Com
