    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。 X$pJ :M{F$  
    `g})|Gx  
    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: (~en (  
    enableservice('AutomationServer', true) TU7' J  
    enableservice('AutomationServer') X|8c>_}  
    ##o#eZq:"  
    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 FE{FGM q  
    Y DFyX){  
    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: 1r7y]FyH$  
    1. 在FRED脚本编辑界面找到参考. 6DWgl$[[  
    2. 找到Matlab Automation Server Type Library #V}IvQl|  
    3. 将名字改为MLAPP e!r-+.i(  
    3{h_&Gbo'D  
    ,u g@f-T  
    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。 2>H24F

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6u}</>}  
    1. 创建Matlab服务器。 ;Q&5,< N)j  
    2. 移动探测面对于前一聚焦面的位置。 Y5d\d\e/  
    3. 在探测面追迹光线 Ib0ZjX6  
    4. 在探测面计算照度 =kqt   
    5. 使用PutWorkspaceData发送照度数据到Matlab kM@zyDn,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Fr$5RAyg  
    7. 用Matlab画出照度数据 pO.2<  
    8. 在Matlab计算照度平均值 RAK-UN  
    9. 返回数据到FRED中 jb;hcraR
