    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。 [Q =N n  
    OB7hlW  
    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: b[yiq$K/  
    enableservice('AutomationServer', true) DMS! a$4  
    enableservice('AutomationServer') eQ"E   
    +RXoi2"-q@  
    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 #%s#c0TX

    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: r/sNrB1U"y  
    1. 在FRED脚本编辑界面找到参考. p7Cs.2>M>S  
    2. 找到Matlab Automation Server Type Library 7KPwQ?SjT  
    3. 将名字改为MLAPP -hV*EPQ/

    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。 />Nt[o[r

    3. 在探测面追迹光线 jIF |P-  
    4. 在探测面计算照度 DN/YHSYK  
    5. 使用PutWorkspaceData发送照度数据到Matlab &?vgP!d&M  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vj*%Q(E6Pt  
    7. 用Matlab画出照度数据 ,P Z ge
