    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。 q329z>  
    qkZ5+2m  
    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: i75?*ld  
    enableservice('AutomationServer', true) $A5B{2  
        enableservice('AutomationServer') K{`2jK#  
    Huug_E+  
    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 ~]m@k'n  
     P %U9S  
    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: m,kv EQ3  
    1. 在FRED脚本编辑界面找到参考. <Bob#Tf ~  
    2. 找到Matlab Automation Server Type Library pU'`9f Li_  
        3. 将名字改为MLAPP N'Z_6A*-  
         XQ+-+CD  
          \!' {-J  
    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。 PEwW*4Xo
