    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。 g/q$;cB  
    XabrX|B#  
    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: [vaG{4m  
    enableservice('AutomationServer', true) *X;g Y  
    enableservice('AutomationServer') ;61m  
    t747SZWgB  
    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 4[!&L:tR  
    ~5wCehSb  
    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: 1*r {%6  
    1. 在FRED脚本编辑界面找到参考. .6 E7 R  
    2. 找到Matlab Automation Server Type Library Ac.z6]p  
    3. 将名字改为MLAPP XY| -qd}A

    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。 " I@Z:[=2

    4. 在探测面计算照度 \FTv N  
    5. 使用PutWorkspaceData发送照度数据到Matlab DI}h?Uf ,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _uHyE }d  
    7. 用Matlab画出照度数据 4:<0i0)5  
    8. 在Matlab计算照度平均值 >CPkL_@VZ=
