    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。 ~nrK>%  
    BaSZ71>9]r  
    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: SzjkI+-$:  
    enableservice('AutomationServer', true) huJ&]"C  
    enableservice('AutomationServer') .u4 W /  
    :P<]+\m  
    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 ch0{+g&  
     #`o2Z  
    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: %d?cP}V  
    1. 在FRED脚本编辑界面找到参考. CbwJd5tk  
    2. 找到Matlab Automation Server Type Library BZR:OtR^  
    3. 将名字改为MLAPP EJsM(iG]~M

    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。 h&--,A >

    4. 在探测面计算照度 A1.7 O

    6. 使用PutFullMatrix发送标量场数据到Matlab中 )XYv}U   
    7. 用Matlab画出照度数据 pKit~A,Q  
    8. 在Matlab计算照度平均值 J/[=p<I)  
    9. 返回数据到FRED中 YbTxn="_
