    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。 WST8SEzJ  
    = \'}g?  
    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: b{L/4bu  
    enableservice('AutomationServer', true) :N4t49i  
    enableservice('AutomationServer') :.Jf0  
    HCyv]LR  
    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 r'^Hg/Jzt  
    }1Gv)l7  
    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: Z>)Bp /-  
    1. 在FRED脚本编辑界面找到参考. jQ2Ot<  
    2. 找到Matlab Automation Server Type Library 'ig&$fzb  
    3. 将名字改为MLAPP w<Wf?aG

    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。 o4m\~as)Y

    1. 创建Matlab服务器。 q"\Z-D0B4

    6. 使用PutFullMatrix发送标量场数据到Matlab中 C-Q28lD}f  
    7. 用Matlab画出照度数据 F5P[dp-`1  
    8. 在Matlab计算照度平均值 wSa)*]%
