    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。 `6A"e Da  
    d~8Q)"6 [  
    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: a srkuAS  
    enableservice('AutomationServer', true) |&JL6hN  
    enableservice('AutomationServer') tv2dyC&a  
    cg~FW2Q  
    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 _W+TZa@_

    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: 5c#L6 dA)  
    1. 在FRED脚本编辑界面找到参考.  ,Y!)V  
    2. 找到Matlab Automation Server Type Library 'e)t+  
    3. 将名字改为MLAPP Oq("E(z+f

    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。 yZ{YIy~

    4. 在探测面计算照度 m^7pbJ\|  
    5. 使用PutWorkspaceData发送照度数据到Matlab "@n$(-.  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Cur) |  
    7. 用Matlab画出照度数据 =p"0G%+%
