    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。 *pP"u::S  
    LoHWkNZ5:  
    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: L5T)_iQ5  
    enableservice('AutomationServer', true) *F:]mgg  
    enableservice('AutomationServer') zc J]US  
    r0G#BPgdR  
    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 v,vTRrpK

    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: MSeO#X  
    1. 在FRED脚本编辑界面找到参考. o0-e,F>u  
    2. 找到Matlab Automation Server Type Library WA Y<X:|We  
    3. 将名字改为MLAPP c Yx=8~-

    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。 qU8UKIP

    4. 在探测面计算照度 _if&a'  
    5. 使用PutWorkspaceData发送照度数据到Matlab PL~k `L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 UShn)3F  
    7. 用Matlab画出照度数据 xHsH .f_{
