    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。 FWq 6e,  
    i8Yl1nF  
    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: ipw_AC~  
    enableservice('AutomationServer', true) F, %qG,  
    enableservice('AutomationServer') ]J~37 35]  
    G5kM0vs6L  
    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 E )09M%fe

    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: J=Ak+  J  
    1. 在FRED脚本编辑界面找到参考. 9K Ih}Q@P  
    2. 找到Matlab Automation Server Type Library />FrMz8;(  
    3. 将名字改为MLAPP Q`,D#V${D

    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。 7h&$^

    1. 创建Matlab服务器。 {5#P1jlT

    4. 在探测面计算照度 TEh]-x`  
    5. 使用PutWorkspaceData发送照度数据到Matlab  !|9$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5w@  ;B  
    7. 用Matlab画出照度数据 x98LOO  
    8. 在Matlab计算照度平均值 uQ vW@Tt
