    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。 (mIw3d8Tz  
    u*0Ck*pZ  
    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: Lgl%fO/<t  
    enableservice('AutomationServer', true) jFfuT9oId  
    enableservice('AutomationServer') Ge=+ 0W)&  
    ;LM`B^Q]s  
    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 WrBiAh,  
    "pGSz%i-  
    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: o8c4h<,  
    1. 在FRED脚本编辑界面找到参考. [`^5Zb  
    2. 找到Matlab Automation Server Type Library 6jT+kq)  
    3. 将名字改为MLAPP 3:1 h:Yc<

    O+hN?/>v  
    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。 ` MtI>x c

    5. 使用PutWorkspaceData发送照度数据到Matlab =z`GC1]bL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ,q$'hYTaJ  
    7. 用Matlab画出照度数据 KLi&T mIB
