    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。 ;wfH^2HxE)  
    *%;6P5n%  
    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: r*xq(\v  
    enableservice('AutomationServer', true) =xl7vHn7  
    enableservice('AutomationServer') A-}PpH~.Z  
    ^BQ>vI'.4  
    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 *'s&/vEy

    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: zp}yiE!bl  
    1. 在FRED脚本编辑界面找到参考. J*/$ywI  
    2. 找到Matlab Automation Server Type Library Ti /;|lP@  
    3. 将名字改为MLAPP jD$;q7fB

    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。 "bL P3

    6. 使用PutFullMatrix发送标量场数据到Matlab中 Nu>sp,|A  
    7. 用Matlab画出照度数据 $@XPL~4  
    8. 在Matlab计算照度平均值 bL6L-S  
    9. 返回数据到FRED中 7] R6
