    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。 m?(8T|i  
    tLu&3<%  
    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: T >8P1p@A,  
    enableservice('AutomationServer', true) f30J8n"k  
    enableservice('AutomationServer') !Ubm 586!  
    D1rVgM  
    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 -+ByK#<%

    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: P3"R2-  
    1. 在FRED脚本编辑界面找到参考. ,' k?rQ  
    2. 找到Matlab Automation Server Type Library F;Q,cg M  
    3. 将名字改为MLAPP _r-LX"

    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。 |mt W)
