    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。 "JzQCY^C  
    E=+v1\t)]  
    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: <E[X-S%&  
    enableservice('AutomationServer', true) *"2TT})   
        enableservice('AutomationServer') sg RY`U.C  
    b`)^Ao:  
    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 N&n2\Y  
    I@76ABu^  
    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: (sSMH6iCif  
    1. 在FRED脚本编辑界面找到参考. *_ {w0U)  
    2. 找到Matlab Automation Server Type Library VC,wQb1J/  
        3. 将名字改为MLAPP  df;-E  
         f^z/s6I0  
         t&MJSFkiA  
    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。 |}P4Gr}6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^kA^> vi  
    1. 创建Matlab服务器。 u^&2T(xG i  
    2. 移动探测面对于前一聚焦面的位置。  [R:\  
    3. 在探测面追迹光线 8(J&_7u  
    4. 在探测面计算照度 KAH9?zI)M  
    5. 使用PutWorkspaceData发送照度数据到Matlab H}5zKv.T  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 U2l7@uDr;  
    7. 用Matlab画出照度数据 AC :cV='  
    8. 在Matlab计算照度平均值 m08:EX P  
    9. 返回数据到FRED中 z'OY6
