    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。 6j6CA?|  
    7_\sx7h{3  
    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: Nj>6TD81u  
    enableservice('AutomationServer', true) 0zr27ko  
    enableservice('AutomationServer') { ptd OrN  
    w<9rTHG8,  
    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 EwPrh

    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: DU!T#H7  
    1. 在FRED脚本编辑界面找到参考. K{P-+(  
    2. 找到Matlab Automation Server Type Library $f =`fPo  
    3. 将名字改为MLAPP !zE{`H a~  
    yvB]rz} i  
    RAO+<m  
    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。 >-MnB

    1. 创建Matlab服务器。 B"GC|}N )v  
    2. 移动探测面对于前一聚焦面的位置。 D^[l~K  
    3. 在探测面追迹光线 /I7V\  
    4. 在探测面计算照度 6eSo.@*l  
    5. 使用PutWorkspaceData发送照度数据到Matlab { W,5]-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7h 54j  
    7. 用Matlab画出照度数据 ZsP^<  
    8. 在Matlab计算照度平均值 s>>&3jfM  
    9. 返回数据到FRED中 Ypyi(_G(?>
