    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。 `)n4I:)2  
    != ,4tg`  
    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: d7X&3L%Oq  
    enableservice('AutomationServer', true) zzQWHg]/  
    enableservice('AutomationServer') '3(^Zv  
    ,JV0ib,  
    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 |/*Pimk

    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: y~ =H`PAE  
    1. 在FRED脚本编辑界面找到参考. J/?Nf2L4  
    2. 找到Matlab Automation Server Type Library Bvn3:+(47  
    3. 将名字改为MLAPP $>XeC}"x68

    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。 } p'ZMj&
