    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。  }t}y  
    7}>7@W8  
    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: UfcQFT{()  
    enableservice('AutomationServer', true) f& P'Kxj_  
    enableservice('AutomationServer') t]LOBy-Kv  
    X}*\/(fzl  
    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 T.\=R

    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: 53efF bo  
    1. 在FRED脚本编辑界面找到参考. o ?z A'5q  
    2. 找到Matlab Automation Server Type Library yClX!OL  
    3. 将名字改为MLAPP &`+tWL6L

    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。 <4r3ZV;'
