    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。 unew XHA  
    Rvx 7}ZL!  
    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: *<y9.\z Y<  
    enableservice('AutomationServer', true) 2,`X@N`\  
    enableservice('AutomationServer') u)I\R\N  
    k'H[aYMA  
    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 {FKr^)g  
    #$-?[c$>  
    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: : [328X2  
    1. 在FRED脚本编辑界面找到参考. u_ l?d  
    2. 找到Matlab Automation Server Type Library j~K(xf  
    3. 将名字改为MLAPP 6QbDU[  
    @KU;' th  
    8IQ}%|lN  
    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。 ,>7dIJqzw
