    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。 k_OzkEM9!  
    sw(|EZ7F  
    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: \%W"KLP  
    enableservice('AutomationServer', true) (3m^@2i  
    enableservice('AutomationServer') @&Af [X4s  
    6D4u?P,  
    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 Lp{uA4:=K  
    )\izL]=!t  
    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: <5|:QLqy  
    1. 在FRED脚本编辑界面找到参考. wX@g >(  
    2. 找到Matlab Automation Server Type Library PC?XE8o  
    3. 将名字改为MLAPP g`=Z%{z%  
    c`)[-  
    @7?L+.r$9  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 z_$F)*PL

    3. 在探测面追迹光线 <)oW  
    4. 在探测面计算照度 u-wj\BU  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5W_Rg:J{P  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 n 8)eC2 A  
    7. 用Matlab画出照度数据 e yByAT~W,  
    8. 在Matlab计算照度平均值 H$3:Ra+ S  
    9. 返回数据到FRED中 F^wm&:%{`
