    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。 CW/L(RQ  
    FDGG$z?>m  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: tuuwoiQ*`  
    enableservice('AutomationServer', true) 1 Qz@  
    enableservice('AutomationServer') 5e0d;Rd  
    q0vZR"y  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Y(?SE< 4R  
    F`{O  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: `Gl[e4U  
    1. 在FRED脚本编辑界面找到参考. Odhr=Hs  
    2. 找到Matlab Automation Server Type Library lq, ]E/<&  
    3. 将名字改为MLAPP zzW$F)X

    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。 &1`Y&x:p

    6. 使用PutFullMatrix发送标量场数据到Matlab中 `P*BW,P'T
