    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。 6+>q1,<  
    [/I4Pe1Yj%  
    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: ,oR}0(^"\<  
    enableservice('AutomationServer', true) 3 *ZE``  
    enableservice('AutomationServer') yB&s2J  
    8[eH8m#~$  
    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 '/mwXvl  
    I~Ziq10  
    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~Lr'UH  
    1. 在FRED脚本编辑界面找到参考. z.FO6y6L  
    2. 找到Matlab Automation Server Type Library )g)X~]*  
    3. 将名字改为MLAPP A+AqlM+$i  
    vU::dr  
    Rb?6N  
    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。 qWdL|8

    3. 在探测面追迹光线 n"* A.  
    4. 在探测面计算照度 JS} iNS'X  
    5. 使用PutWorkspaceData发送照度数据到Matlab *1|&uE&_R  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d=`hFwD9  
    7. 用Matlab画出照度数据 ;BsyN[bF  
    8. 在Matlab计算照度平均值 w(0's'  
    9. 返回数据到FRED中 UH2fP G
