    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。 (Al.hEs'  
    (9h{7<wD`  
    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: Dg]ua5jk  
    enableservice('AutomationServer', true) Yn,dM~|Cc  
    enableservice('AutomationServer') DJeP]  
    v7O&9a;  
    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 uG\ +`[-{0

    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: LSQ2pB2V  
    1. 在FRED脚本编辑界面找到参考. [8/E ;h  
    2. 找到Matlab Automation Server Type Library br"p D-}  
    3. 将名字改为MLAPP t_ &FK A

    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。 dOq*W<%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: x%ZjGDFm  
    1. 创建Matlab服务器。 #.0^;M5Nh  
    2. 移动探测面对于前一聚焦面的位置。 8=Di+r  
    3. 在探测面追迹光线 }io9Hk>|  
    4. 在探测面计算照度 hq/k}Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]*pALT6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u0h {bu  
    7. 用Matlab画出照度数据 @R>4b  
    8. 在Matlab计算照度平均值 3Juhn5&N  
    9. 返回数据到FRED中 FqiC zP4
