    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。 +Vg(2Xt  
    %#% YU|4R  
    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: Q8HNST($?  
    enableservice('AutomationServer', true) )-+tN>Bb  
    enableservice('AutomationServer')  '0f!o&?g  
    -~.+3rcZ]  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 =)y$&Ydj

    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: ]>)}xfL &,  
    1. 在FRED脚本编辑界面找到参考. .NdsKhg b  
    2. 找到Matlab Automation Server Type Library CMC p7- v

    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。 o<b
