    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。 #5h_{q4l  
    SVZ@'X\[M  
    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: l?IeZisX  
    enableservice('AutomationServer', true) #-Mr3  
    enableservice('AutomationServer') {/)i}V#RE  
    @f"[*7Q`/  
    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 1`|Z8Jpocj

    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: T~$Eh6 D  
    1. 在FRED脚本编辑界面找到参考. :FU?vh$)  
    2. 找到Matlab Automation Server Type Library /2d>nj  
    3. 将名字改为MLAPP i._RMl5zg  
    W;T0_=

    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。 3n)Kzexh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d 4tL  
    1. 创建Matlab服务器。 JFc, f  
    2. 移动探测面对于前一聚焦面的位置。 #b&tNZ4!_  
    3. 在探测面追迹光线 z&n2JpLY7  
    4. 在探测面计算照度 "0nsYE  
    5. 使用PutWorkspaceData发送照度数据到Matlab h{_\ok C>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 d3\?:}o,  
    7. 用Matlab画出照度数据 Z'9|  
    8. 在Matlab计算照度平均值 4a& 8G  
    9. 返回数据到FRED中 _#v"sGmN
