    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。 r2"B"%;  
    W!6&T [j>  
    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: /r2*le (H  
    enableservice('AutomationServer', true) kbu.KU+  
    enableservice('AutomationServer') I54`}Npp  
    <u`m4w  
    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 !X5n'1&

    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: *7cc4 wGQ  
    1. 在FRED脚本编辑界面找到参考. \+3amkBe  
    2. 找到Matlab Automation Server Type Library <l>o6K  
    3. 将名字改为MLAPP 0q}k"(9

    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。 bMU0h,|]
