    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。 _NwB7@ e  
    KscugX*x  
    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: &/\Q6$a  
    enableservice('AutomationServer', true) Kw/7X[|'G  
    enableservice('AutomationServer') $\9M6k'  
    $FJf8u`  
    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 Dr_ (u<[  
    3D2\#6yo  
    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: Y8s.Q  
    1. 在FRED脚本编辑界面找到参考. -wdd'G  
    2. 找到Matlab Automation Server Type Library $sfDtnRy  
    3. 将名字改为MLAPP 3hD\6,@

    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。 uE;bNs'

    6. 使用PutFullMatrix发送标量场数据到Matlab中 qX%oLa  
    7. 用Matlab画出照度数据 ^C|N
