    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。 q7I(x_y /  
    "EZpTy}Ee  
    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: Ieh<|O,-C  
    enableservice('AutomationServer', true) xO4""/ n  
        enableservice('AutomationServer') \0FwxsL  
    6$H`wDh#(&  
    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 rrG}; A  
    `4ti?^BNm  
    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: ({cWb:+r  
    1. 在FRED脚本编辑界面找到参考. Us%g&MWdpb  
    2. 找到Matlab Automation Server Type Library PlwM3lrj  
        3. 将名字改为MLAPP /RWD\u<l

         ONF x -U]  
    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。 equi26jhr
