    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。 bHYy}weZ  
    F#Ryu~,"  
    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: 8I?Wt W  
    enableservice('AutomationServer', true) {hjhL: pg  
    enableservice('AutomationServer') K(rWNO  
    TDKki(o=~  
    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 l`{\"#4  
    }5[qo`M  
    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: BwGfTua  
    1. 在FRED脚本编辑界面找到参考. qvsd5PeCO  
    2. 找到Matlab Automation Server Type Library sN*N&XG  
    3. 将名字改为MLAPP X1|njJGO1

    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。 ,j{,h_Op

    1. 创建Matlab服务器。 Q7\w+ANf0  
    2. 移动探测面对于前一聚焦面的位置。 wLH>:yKUU  
    3. 在探测面追迹光线 _\G"9,)u '  
    4. 在探测面计算照度 I\{ 1u  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7 :xfPx  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~{g [<Qi  
    7. 用Matlab画出照度数据 @7]yl&LZ  
    8. 在Matlab计算照度平均值 u@UMP@"#  
    9. 返回数据到FRED中 - t'jNR'
