    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。 8X|r4otn4  
     7R#+Le)  
    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: .`<@m]m-  
    enableservice('AutomationServer', true) z7M_1%DEx  
    enableservice('AutomationServer') wkqX^i7ls  
    [YrHA~=U  
    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 Rm1A>1a :

    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: mI*[>#q>  
    1. 在FRED脚本编辑界面找到参考. !o=U19)  
    2. 找到Matlab Automation Server Type Library r0d35  
    3. 将名字改为MLAPP |tR OL 9b

    ?{w3|Ef&  
    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。 4'4\ ,o

    1. 创建Matlab服务器。 =[\s8XH,

    4. 在探测面计算照度 a22Mufl  
    5. 使用PutWorkspaceData发送照度数据到Matlab \I"Z2N>^z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *_E|@y  
    7. 用Matlab画出照度数据 }g#&Q0  
    8. 在Matlab计算照度平均值 mWR4|1(
