    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。 *(1 <J2j  
    ?xH{7)dO  
    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: M>m!\bb%.  
    enableservice('AutomationServer', true) 2"Wq=qy\J  
        enableservice('AutomationServer') n@ba>m4{  
    v JGH8$%;,  
    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 9%|skTgIqH

    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: 48^C+#Jbc  
    1. 在FRED脚本编辑界面找到参考. 4GF3.?3  
    2. 找到Matlab Automation Server Type Library %n9ukc~$p  
        3. 将名字改为MLAPP rZpsC}C'

    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。 =,;$d&#*h

        6. 使用PutFullMatrix发送标量场数据到Matlab中 ysK J=  
    7. 用Matlab画出照度数据 Ewr2popK  
    8. 在Matlab计算照度平均值 2e1%L,y{W
