    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。 8@I.\u)0  
    <^8OYnp  
    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: )v.\4Q4  
    enableservice('AutomationServer', true) @{880 5Dp  
    enableservice('AutomationServer') 0+S'i82=M  
    y? 65*lUl  
    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 [dXRord

    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: c-a;nAR  
    1. 在FRED脚本编辑界面找到参考. 9, 792b  
    2. 找到Matlab Automation Server Type Library vYG$>*  
    3. 将名字改为MLAPP 7jF2m'(

    !E\J`K0_e  
    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。 Xc]Q_70O
