    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。 3vx5dUgl,  
    up+W[#+  
    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: RTN?[`  
    enableservice('AutomationServer', true) p=F!)TnJN  
    enableservice('AutomationServer') sywSvnPuYZ  
    EfxW^zm)  
    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 Dep.Qfv{-  
    <A{|=2<  
    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: A*d Pw.  
    1. 在FRED脚本编辑界面找到参考. L?~>eT  
    2. 找到Matlab Automation Server Type Library eVL #3|=  
    3. 将名字改为MLAPP 8<BYAHY^

    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。 Lhg4fuos@)

    4. 在探测面计算照度 p mv6m  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ir%L%MuR]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "Zk# bQ2j  
    7. 用Matlab画出照度数据 _v~c3y).  
    8. 在Matlab计算照度平均值 Q-A:0F&{t
