    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。 lND2Kb  
    "\EX)u9ze  
    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: `2]0 X#R  
    enableservice('AutomationServer', true) >I\B_q  
    enableservice('AutomationServer') }(8>&  
    Hc'Pp{| X  
    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 +ZNOvcsV  
    z*h:Nt%.  
    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: iGSJ\  
    1. 在FRED脚本编辑界面找到参考. AC1RP`c  
    2. 找到Matlab Automation Server Type Library BJwuN  
    3. 将名字改为MLAPP %Zk6K!MY#  
    <~5O-.G]  
    I+H~ 5zq.  
    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。 pp"#pl

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Op-z"inw  
    1. 创建Matlab服务器。 ^%,{R},s  
    2. 移动探测面对于前一聚焦面的位置。 Oe;#q  
    3. 在探测面追迹光线 y@7fR9hp<  
    4. 在探测面计算照度 |:5O|m '  
    5. 使用PutWorkspaceData发送照度数据到Matlab Q~nVbj?c2v  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 s0dP3tz>  
    7. 用Matlab画出照度数据 ~BuzI9~7P  
    8. 在Matlab计算照度平均值 N_bgWQY  
    9. 返回数据到FRED中 QUW`Yc
