    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。 aB2F C$z  
    !3c\NbU  
    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: xf\C|@i  
    enableservice('AutomationServer', true) }1L4 "}L.  
    enableservice('AutomationServer') R3)~?X1n  
    ) yi E@ X  
    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 a_^\=&?'  
    n:I,PS0H<  
    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: z>1Pz(  
    1. 在FRED脚本编辑界面找到参考. s0TORl6Z|  
    2. 找到Matlab Automation Server Type Library kUL' 1!j7  
    3. 将名字改为MLAPP ;>U2|>5V

    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。 !]A

    5. 使用PutWorkspaceData发送照度数据到Matlab S1T"Z{$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 K(e$esLs-
