    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。 Z-@}~#E  
    zTLn*?  
    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: F0Hbklr  
    enableservice('AutomationServer', true) 5WT\0]RUa  
    enableservice('AutomationServer') y`\Mhnj  
    +QX>:z  
    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 kP$g 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: sd53 _s V  
    1. 在FRED脚本编辑界面找到参考. =]e^8;e9  
    2. 找到Matlab Automation Server Type Library }=a4uCE  
    3. 将名字改为MLAPP lIg2iun[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。 &F_rg,q&_
