    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。 %S{o5txo  
    o*%3[HmV  
    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: &bB6}H(  
    enableservice('AutomationServer', true) =MMCf0  
    enableservice('AutomationServer') jEZ "  
    )*!1bgXQ  
    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 +->\79<#V(

    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: "3@KRb4f  
    1. 在FRED脚本编辑界面找到参考. Ru)(dvk}S  
    2. 找到Matlab Automation Server Type Library  "\`>2

    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(eW7RL
