    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。 AF qut  
    T&2aNkuG  
    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: T F!Lp:  
    enableservice('AutomationServer', true) 0-^wY8n-=  
    enableservice('AutomationServer') [akyCb  
    2HNH@K  
    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 ]g/% w3G  
    "/)}Cc,L  
    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: C(-bh]J  
    1. 在FRED脚本编辑界面找到参考. q >9F21W  
    2. 找到Matlab Automation Server Type Library ?`hk0qX3  
    3. 将名字改为MLAPP qR~s&SC#

    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。 $h Is ab_
