    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。 ejI nJ  
    pxi/ ]6pw  
    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: 6I,4 6 XZ-  
    enableservice('AutomationServer', true) GK-__Y.  
    enableservice('AutomationServer') 3# r` e  
    VA0p1AD  
    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< Ini'od[

    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: E]IPag8C  
    1. 在FRED脚本编辑界面找到参考. v^QUYsar  
    2. 找到Matlab Automation Server Type Library b\H !\A  
    3. 将名字改为MLAPP ]^ "BLbDZ@

    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。 *^b<CZd9

    4. 在探测面计算照度 T)"LuC#C  
    5. 使用PutWorkspaceData发送照度数据到Matlab =h se2f  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |g}~7*+i  
    7. 用Matlab画出照度数据 I3$/ #  
    8. 在Matlab计算照度平均值 bEc @"^)  
    9. 返回数据到FRED中 MY `V0
