    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。 o,* D8[  
    j4!O,.!T  
    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: ty pbwfM]  
    enableservice('AutomationServer', true) S5y.H  
        enableservice('AutomationServer') 5Lej_uqF   
    B,w ZI4oi*  
    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 .1{{E8Fj

    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: (?zD!% k  
    1. 在FRED脚本编辑界面找到参考. /9I/^i~  
    2. 找到Matlab Automation Server Type Library \i%mokfbc  
        3. 将名字改为MLAPP 3)\fZYu)  
         NId.TaXh  
         tLfhW1"  
    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。 lNa+NtQu

    4. 在探测面计算照度 G`>]ng  
    5. 使用PutWorkspaceData发送照度数据到Matlab .\^0RyJE  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 uu,F5<y[  
    7. 用Matlab画出照度数据 TxP +?1t  
    8. 在Matlab计算照度平均值 Xzf,S;XV~  
    9. 返回数据到FRED中 jj2\;b:a0
