    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。 i >BQRbU  
    ]!WD">d:  
    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: F^cu!-L  
    enableservice('AutomationServer', true) fLuOxYQbf  
    enableservice('AutomationServer') Htce<H-P  
    [h0)V(1KR  
    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 MVp+2@)}s  
    IG4`f~k^  
    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: =qww|B92  
    1. 在FRED脚本编辑界面找到参考. lkQ(?7  
    2. 找到Matlab Automation Server Type Library BHS8MV L@  
    3. 将名字改为MLAPP GOX2'N\h^

    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。 nO8e'&|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: LC0g"{M  
    1. 创建Matlab服务器。 er2#h  
    2. 移动探测面对于前一聚焦面的位置。 H|<Zm:.%$  
    3. 在探测面追迹光线 YDGW]T]i ?  
    4. 在探测面计算照度 BBj>ML\X  
    5. 使用PutWorkspaceData发送照度数据到Matlab awOH50R  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #!w7E,UBi  
    7. 用Matlab画出照度数据 lR5k1J1n  
    8. 在Matlab计算照度平均值 +wm%`N;v<  
    9. 返回数据到FRED中 Gi,4PD-ro
