    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。 /g>-s&w  
    IoOOS5a  
    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(c9I)  
    enableservice('AutomationServer', true) w98M #GqV  
        enableservice('AutomationServer') 6V$ )ym*F  
    nmiJ2edx  
    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 *~P| ? D'  
    3?j: M]fR  
    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: z&H.fsL  
    1. 在FRED脚本编辑界面找到参考. !IR cv a  
    2. 找到Matlab Automation Server Type Library #+D][LH4  
        3. 将名字改为MLAPP 2 )o2d^^

    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。 T&[6
