    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~3 A>j  
    1djZ5`+  
    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: `YNzcn0x  
    enableservice('AutomationServer', true) 2"IV  
    enableservice('AutomationServer') 19E(Hsz  
    (GJtTp~2C4  
    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 }Fe6L;^;  
    j4~(6Imm  
    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: L'+bVP{L  
    1. 在FRED脚本编辑界面找到参考. eh86-tQI~(  
    2. 找到Matlab Automation Server Type Library %7#<K\])  
    3. 将名字改为MLAPP gRLt0&Q~

    N!+=5!  
    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。 uNyU]@R<W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Q i18q|l8v  
    1. 创建Matlab服务器。 dyQ7@K.E  
    2. 移动探测面对于前一聚焦面的位置。 jPWONz(#  
    3. 在探测面追迹光线 %3z[;&*3O  
    4. 在探测面计算照度 DbMVbgz<e  
    5. 使用PutWorkspaceData发送照度数据到Matlab z?byNd8  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JRl=j2z  
    7. 用Matlab画出照度数据 ]s\r3I]  
    8. 在Matlab计算照度平均值 B/a gW  
    9. 返回数据到FRED中 OSBR2Z;=
