    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。 }+GIrEDId  
    Ydh+iLjhx  
    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: h0zv @,u  
    enableservice('AutomationServer', true) ]Jx_bs~g  
        enableservice('AutomationServer') M I R))j;  
    i-`J+8|d  
    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 ]E}eM@xdD  
    [D<"qT^*z6  
    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: 1YvE/<6  
    1. 在FRED脚本编辑界面找到参考. {4HcecT  
    2. 找到Matlab Automation Server Type Library {7LNQGiJ  
        3. 将名字改为MLAPP XjU/7Q

         "\l#q$1h  
    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。 oaM 3#QJ

    4. 在探测面计算照度 nn{PhyK  
    5. 使用PutWorkspaceData发送照度数据到Matlab R}HNi(%"  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 tY!GJusd  
    7. 用Matlab画出照度数据 oS#PBql4  
    8. 在Matlab计算照度平均值 zF#:Uc`C5U
