    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。 *xU^e`P  
    68)z`JI|<)  
    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: / vje='[!  
    enableservice('AutomationServer', true) Zu\#;O   
        enableservice('AutomationServer') < 5[wP)K@  
    k'%c|kx8U  
    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 D}cq_|mmn[

    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: `W?aq]4x5  
    1. 在FRED脚本编辑界面找到参考. ^67P(h  
    2. 找到Matlab Automation Server Type Library 1oj7R7  
        3. 将名字改为MLAPP _\sm$ `q

    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。 Wz:MPdz3(

    4. 在探测面计算照度 Sqc*u&W  
    5. 使用PutWorkspaceData发送照度数据到Matlab t}nZrD  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 .b  N0!  
    7. 用Matlab画出照度数据 z~o%U&DO}
