    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。 es*_Oo1  
    IPr*pQ{;c  
    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: ` $QzTv   
    enableservice('AutomationServer', true) $=@9 D,R  
    enableservice('AutomationServer') ;f\R$u-  
    Y_|K,T6Zj@  
    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 cNuuzA

    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: : . FfE  
    1. 在FRED脚本编辑界面找到参考. 0pZ.; /<{  
    2. 找到Matlab Automation Server Type Library utFcFd X  
    3. 将名字改为MLAPP #%} u8\q

    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(?'Yy

    3. 在探测面追迹光线 RT_Pd\(qD

    6. 使用PutFullMatrix发送标量场数据到Matlab中 t?#vb}_  
    7. 用Matlab画出照度数据 ;s!ns N  
    8. 在Matlab计算照度平均值 !X v2PdP  
    9. 返回数据到FRED中 `Q(]AG I2
