    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。 u8@>ThPD  
    doaqHri\,  
    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: _qqJ>E<0  
    enableservice('AutomationServer', true) l,3[hx  
    enableservice('AutomationServer') uw@|Y{(K r  
    Yt;.Z$i ,  
    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 -n~VMLd?@  
    yf6&'Y{  
    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: n-_-;TYH  
    1. 在FRED脚本编辑界面找到参考. Djf,#&j!3  
    2. 找到Matlab Automation Server Type Library ouUU(jj02  
    3. 将名字改为MLAPP  3^zO G2  
    ) 4'@=q  
    JEes'H}Y  
    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。 Gwkp(9d

    现在将脚本代码公布如下,此脚本执行如下几个步骤: W;C41>^?/  
    1. 创建Matlab服务器。 Wz7jB6AWA

    5. 使用PutWorkspaceData发送照度数据到Matlab s0"1W"7vh  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?o9g5Z  
    7. 用Matlab画出照度数据 Rj=xn(@d
