    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。 > '.[G:b  
    }Q ;BQ2[  
    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: Q2FQhc@L(:  
    enableservice('AutomationServer', true) G1TANy  
        enableservice('AutomationServer') o Fi) d[`  
    )tCx5 9  
    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 X]MTaD.t  
    ~Q0&P!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: N:7.:Yw  
    1. 在FRED脚本编辑界面找到参考. Yq{jEatY{/  
    2. 找到Matlab Automation Server Type Library >-eS&rma  
        3. 将名字改为MLAPP U(!?d ]en  
         +dJ&tuL:S  
         Eny!R@u7q  
    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。 oo\IS\

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0yKh p: ^  
    1. 创建Matlab服务器。 xmOM<0T  
    2. 移动探测面对于前一聚焦面的位置。 CxkMhd8qz  
    3. 在探测面追迹光线 l*qk1H"g  
    4. 在探测面计算照度 3+j^E6@  
    5. 使用PutWorkspaceData发送照度数据到Matlab PH[4y:^DN  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 z41D^}b  
    7. 用Matlab画出照度数据 4':MI|/my_  
    8. 在Matlab计算照度平均值 9V.+U7\w  
    9. 返回数据到FRED中 ZDfS0]0F
