    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。 n+k,:O5  
     "+Sq}WR  
    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: ]kF1~kXBe  
    enableservice('AutomationServer', true) @3bVjQ`4f  
    enableservice('AutomationServer') vb}c)w dp?  
    Fqh./@o  
    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 e&!8UYP

    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: nC)"% Sa  
    1. 在FRED脚本编辑界面找到参考. s-~`Ao' <  
    2. 找到Matlab Automation Server Type Library (^E5y,H<g  
    3. 将名字改为MLAPP VCvf'$4(X

    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。 4vCUVo r

    3. 在探测面追迹光线 Ge^,hAM'  
    4. 在探测面计算照度 X-J85b_e  
    5. 使用PutWorkspaceData发送照度数据到Matlab NQqNBI?cr  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $aN%[  
    7. 用Matlab画出照度数据 5".bM8o  
    8. 在Matlab计算照度平均值 2<:dA >1  
    9. 返回数据到FRED中 zS h9`F
