    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。 pLtw|S'4  
    U\tx{CsSz  
    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: 0zB[seyE  
    enableservice('AutomationServer', true) </`\3t  
    enableservice('AutomationServer') SI+Uq(k  
    ([dd)QU  
    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 q_h (D/g  
    p|ink):  
    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: @nY]S\if  
    1. 在FRED脚本编辑界面找到参考. 0>N6.itOz  
    2. 找到Matlab Automation Server Type Library Wq1 jTIQ  
    3. 将名字改为MLAPP TjEXR$:<  
    g gx_h  
    PVBz~rG  
    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。 j/*1zu8Y
