    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。 z$66\/V']  
    ",T` \8&@e  
    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: a&N%|b K  
    enableservice('AutomationServer', true) YQ+^  
    enableservice('AutomationServer') P sp^@  
    e+l\\9v  
    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 v[smQO

    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: <$Ztik1  
    1. 在FRED脚本编辑界面找到参考. (2d3jQN`  
    2. 找到Matlab Automation Server Type Library 1g~y]iQ  
    3. 将名字改为MLAPP ZJ9x6|q

    5=Suj*s{D#  
    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(rK^RT

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~o i)Lf1  
    1. 创建Matlab服务器。 ydB$4ZB3[  
    2. 移动探测面对于前一聚焦面的位置。 4T%cTH:.9N  
    3. 在探测面追迹光线 s%^o*LQ|9  
    4. 在探测面计算照度 aiJnfU]W  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2uEhOi0I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 gJKKR]4*  
    7. 用Matlab画出照度数据 \q,s?`+B  
    8. 在Matlab计算照度平均值 i%MA"I\9  
    9. 返回数据到FRED中 dqxd3,Z
