    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。 )(|+z'  
    NyTv~8A`)  
    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: ?-P]m&nh|  
    enableservice('AutomationServer', true) H"H&uA9"  
        enableservice('AutomationServer') 5};Nv{km^2  
    4Y[uqn[  
    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 h<50jnH!  
    09{B6l6P  
    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: i-'rS/R  
    1. 在FRED脚本编辑界面找到参考. R&BbXSIDX  
    2. 找到Matlab Automation Server Type Library 85<zl|ZD  
        3. 将名字改为MLAPP 4|*H0}HOm  
         E5P?(5Nv  
         |7V:~MTkk&  
    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。 4%TY` II

    4. 在探测面计算照度 h^h!OQKQ

        6. 使用PutFullMatrix发送标量场数据到Matlab中 6_a42#  
    7. 用Matlab画出照度数据 E}aTH
