    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。 E~P 0}'  
    ("6W.i>  
    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: Y P c<  
    enableservice('AutomationServer', true) SDwSlwf  
    enableservice('AutomationServer') z,)sS<t(  
    QFPx4F7(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 B`aAvD`7

    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: >C[1@-]G%7  
    1. 在FRED脚本编辑界面找到参考. A]9JbNV

    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。  aC: l;

    4. 在探测面计算照度 >G2-kL_  
    5. 使用PutWorkspaceData发送照度数据到Matlab P{eRDQ=
