    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。 ^@Y9!G=  
    rNxG0^k(  
    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: d4V 2[TX  
    enableservice('AutomationServer', true) E s:5yX!  
    enableservice('AutomationServer') $Uy#/MX  
    uzO {{S-  
    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 L*IU0Jy>

    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: qb9}&'@:  
    1. 在FRED脚本编辑界面找到参考. pBvo M={2!  
    2. 找到Matlab Automation Server Type Library p>!1S  
    3. 将名字改为MLAPP qjzZ}

    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。 <G&WYk%u*
