    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。 *GbC`X)  
    5(1Zj`>'  
    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: wg^#S  
    enableservice('AutomationServer', true) ;{ XKZ}  
        enableservice('AutomationServer') yX$I<L<Suz  
    Xlw&hKS  
    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 WfBA5

    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: djS?$WBpU  
    1. 在FRED脚本编辑界面找到参考. :HYqm*v;W  
    2. 找到Matlab Automation Server Type Library @y;N u   
        3. 将名字改为MLAPP ~1`.iA

    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。 Pr{?A]dQ

    5. 使用PutWorkspaceData发送照度数据到Matlab ! o:m*:  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 &}nU#)IX  
    7. 用Matlab画出照度数据 Qpndi$2H!
