    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。 {mJ' Lb0;  
    Vc9rc}  
    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: F}}!e.>c  
    enableservice('AutomationServer', true) _qa]T'8  
    enableservice('AutomationServer') q!c=f!U?\l  
    @s1T|}AJ  
    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 G!6b )4L-  
    t5+p]7  
    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: CGi;M=xr  
    1. 在FRED脚本编辑界面找到参考. !i"zM}  
    2. 找到Matlab Automation Server Type Library M.Yp'Av  
    3. 将名字改为MLAPP !h.hJt

    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。 y > =Y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: wOf8\s1  
    1. 创建Matlab服务器。 fmixWL7.Zg  
    2. 移动探测面对于前一聚焦面的位置。 ~2Wus8X-  
    3. 在探测面追迹光线 IAQ<|3Q  
    4. 在探测面计算照度 tczJk1g}  
    5. 使用PutWorkspaceData发送照度数据到Matlab <[[yV  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 VO0:4{-  
    7. 用Matlab画出照度数据 2fTuIS<yr  
    8. 在Matlab计算照度平均值 q}Q G<%VR  
    9. 返回数据到FRED中 $9X+dvu*
