    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。 8zc!g|5"  
    c"YK+2  
    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: {cv;S2  
    enableservice('AutomationServer', true) *.*:(7`  
    enableservice('AutomationServer') -Y[-t;  
    4 P;O8KA5y  
    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 }-L@AC/\#

    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: =P#!>*\ar  
    1. 在FRED脚本编辑界面找到参考. yQA[X}  
    2. 找到Matlab Automation Server Type Library (Z$6J Nkz  
    3. 将名字改为MLAPP &!a 2%%1#N

    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。 Az-!LAu9 R

    2. 移动探测面对于前一聚焦面的位置。 ->hxHr`!%a  
    3. 在探测面追迹光线 Cv~hU%1T  
    4. 在探测面计算照度 cx,A.Lc  
    5. 使用PutWorkspaceData发送照度数据到Matlab Zd(d]M_x  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 S1zw'!O5  
    7. 用Matlab画出照度数据 :'dc=C  
    8. 在Matlab计算照度平均值 M([H\^\:  
    9. 返回数据到FRED中 7S2F^,w
