    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。 aYc^ 9*7  
    /-+hMYe  
    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: 2AEVBkF;M  
    enableservice('AutomationServer', true) xl@~K^c]  
    enableservice('AutomationServer') b,>>E^wd!  
    4zZ.v"laVM  
    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 ZVrZkd `

    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: U.Y7]#P:  
    1. 在FRED脚本编辑界面找到参考. `A-  
    2. 找到Matlab Automation Server Type Library ]Qe"S>,?`  
    3. 将名字改为MLAPP FuG;$';H75

    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。 8Y:x+v5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *;U<b  
    1. 创建Matlab服务器。 i1*0'x  
    2. 移动探测面对于前一聚焦面的位置。 rbl^ aik  
    3. 在探测面追迹光线 x~K79Mya  
    4. 在探测面计算照度 o'8nQ Tao  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7xfS%'=y"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /QQjb4S}  
    7. 用Matlab画出照度数据 ?# RhHD  
    8. 在Matlab计算照度平均值 :>F3es`  
    9. 返回数据到FRED中 k$>5v +r0
