    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。 xaG( 3  
    \DC0`  
    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: `}Z`aK  
    enableservice('AutomationServer', true) \&Zp/;n  
    enableservice('AutomationServer') TtKV5  
    ydm2'aV  
    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 T z?0E"yx

    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: /l&$B  
    1. 在FRED脚本编辑界面找到参考. sOUQd-!"  
    2. 找到Matlab Automation Server Type Library oW \k%Vj  
    3. 将名字改为MLAPP gJC~$/2

    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。 r#X6jU

    5. 使用PutWorkspaceData发送照度数据到Matlab o;5ns  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \\UOpl  
    7. 用Matlab画出照度数据 gql^Inx<  
    8. 在Matlab计算照度平均值 h1AZ+9
