    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。 xv4nYm9  
    bTHJbpt*-  
    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: -W+dsZ Sv8  
    enableservice('AutomationServer', true) g6 7*Bs  
        enableservice('AutomationServer') g.F{yX]  
    ~aA+L-s|  
    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 Haq23K

    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: oY+RG|j@  
    1. 在FRED脚本编辑界面找到参考. R`TM@aaS:  
    2. 找到Matlab Automation Server Type Library e|+uLbN&;c  
        3. 将名字改为MLAPP `z+:Z>>

    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。 My)}oN7\z

        6. 使用PutFullMatrix发送标量场数据到Matlab中 x%cKTpDh!  
    7. 用Matlab画出照度数据 M{O2O(
