    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。 Od?b(bE.]  
    {sR|W:fS$  
    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: hAvX{]  
    enableservice('AutomationServer', true) ?E|be )  
    enableservice('AutomationServer') sI% =G3o=  
    %AV[vr,  
    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 &`}8Jz=S

    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: AZ'"Ua  
    1. 在FRED脚本编辑界面找到参考. .8~zgpK  
    2. 找到Matlab Automation Server Type Library dp=#|!jc  
    3. 将名字改为MLAPP qCUn. mI

    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。 cpJ(77e

    4. 在探测面计算照度 j%TcW!D-_  
    5. 使用PutWorkspaceData发送照度数据到Matlab okSCM#&:[2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =zX A0%  
    7. 用Matlab画出照度数据 kA/V=xO<  
    8. 在Matlab计算照度平均值 s<`54o ,  
    9. 返回数据到FRED中 laX67Vjv
