    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。 jUBlIVl]  
    x%cKTpDh!  
    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: 0FEb[+N  
    enableservice('AutomationServer', true) ]Ms~;MXlx5  
        enableservice('AutomationServer') IXd&$h]Lq  
    r"5]U`+  
    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 pjbKMx

    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: Kpj0IfC,10  
    1. 在FRED脚本编辑界面找到参考. Z)6bqU<LQE  
    2. 找到Matlab Automation Server Type Library   ;h  
        3. 将名字改为MLAPP I"<~!krt%

    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。 o Q{gh$6*

    2. 移动探测面对于前一聚焦面的位置。 Ev$?c9*>  
    3. 在探测面追迹光线 {#Gr=iv~N  
    4. 在探测面计算照度 tYmWze. j  
    5. 使用PutWorkspaceData发送照度数据到Matlab I?F^c6M=  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 RQ/X{<lQ)  
    7. 用Matlab画出照度数据 7/aJ?:gX  
    8. 在Matlab计算照度平均值 ??1V__w
