    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。 WG luY>C;  
    Kn$1W=B1.  
    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: Q3q.*(#  
    enableservice('AutomationServer', true) R<HZC;x  
    enableservice('AutomationServer') 5 hadA>d  
    l_-n&(N2<[  
    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 cEjdImAzU  
    n{r#K_  
    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: 08?MS_  
    1. 在FRED脚本编辑界面找到参考. xBfe8lor  
    2. 找到Matlab Automation Server Type Library U hhmG+  
    3. 将名字改为MLAPP 0_mvz%[J

    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。 {/xs9.8:JX

    7. 用Matlab画出照度数据 {3(.c, q@  
    8. 在Matlab计算照度平均值 9r+O!kF(
