    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。 nR8r$2B+t  
    KZGy&u >`  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:  i)= \-C  
    enableservice('AutomationServer', true) V,&A? Y  
        enableservice('AutomationServer') (D2N_l(`<  
    k\Z7Dg$\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 (O"-6`w[  
    :: s k)  
    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: IsiBn(1Z  
    1. 在FRED脚本编辑界面找到参考. odKdpa Zc[  
    2. 找到Matlab Automation Server Type Library J~|:Q.Rt`  
        3. 将名字改为MLAPP tL]T_]z  
         z!aU85y  
         Y3O/`-9i  
    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。 EIF"{,m

    4. 在探测面计算照度 M8${&&[;

        6. 使用PutFullMatrix发送标量场数据到Matlab中 BG/RNem  
    7. 用Matlab画出照度数据 \G2PK&)F
