    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。 <ni_78  
    A"e4w?  
    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: 5cvvdO*C0  
    enableservice('AutomationServer', true) #<LJns\t   
    enableservice('AutomationServer') ZveNe~D7C  
    ,i jB3J  
    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 &SG5 f[

    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: eRqPZb"6MR  
    1. 在FRED脚本编辑界面找到参考. r|63T%q!  
    2. 找到Matlab Automation Server Type Library 4s e6+oJe  
    3. 将名字改为MLAPP jY2mn".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。 3PjX;U|
