    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。 O=St}B\!m  
    K_B-KK(^  
    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: $9\!CPZ2  
    enableservice('AutomationServer', true) 3say&|kJ  
        enableservice('AutomationServer') Y m|zM1qc  
    Ro?a DrQ  
    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;<=aa)}?  
    9Qb_BNUo  
    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: i4N '[ P}  
    1. 在FRED脚本编辑界面找到参考. 6nRD:CH)X  
    2. 找到Matlab Automation Server Type Library i1 ?H*:]  
        3. 将名字改为MLAPP ]J C}il_b  
         T?c:z?j_9  
         DxT8;`I%  
    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。 2, ` =i

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Xb=9~7&,$  
    1. 创建Matlab服务器。 P-VK=Y1q  
    2. 移动探测面对于前一聚焦面的位置。 W9?Vh{w  
    3. 在探测面追迹光线 [(Pm\o  
    4. 在探测面计算照度 w7 ]@QTC  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0t1WvW  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Z*QsDS  
    7. 用Matlab画出照度数据 4*_9Gl  
    8. 在Matlab计算照度平均值 @U(D&_H,K  
    9. 返回数据到FRED中 YZdp/X6x
