    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。 a8M.EFa:  
    OzBo *X/p  
    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: +A W6 >yV`  
    enableservice('AutomationServer', true) ^T'+dGU`  
    enableservice('AutomationServer') FMY r6/I  
    $>'}6?C.  
    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 9;dP7o

    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: %s$_KG!&  
    1. 在FRED脚本编辑界面找到参考. Xn.zN>mB  
    2. 找到Matlab Automation Server Type Library e;x`C  
    3. 将名字改为MLAPP L6BHh_*E  
    "V~U{(Z  
    +;#hED; 8  
    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]n5pZ\\W<
