    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。 b_q! >&c  
    Z4=_k{*  
    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: is64)2F](  
    enableservice('AutomationServer', true) bb*c+XN0  
    enableservice('AutomationServer') }{P&idkv  
    nR(#F9  
    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  fF\*v  
    GOUY_&}tL  
    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: ZCj>MA  
    1. 在FRED脚本编辑界面找到参考. Rd`{qW  
    2. 找到Matlab Automation Server Type Library 2Y9y5[K,F)  
    3. 将名字改为MLAPP t)YFTO"Jj  
    D%6ir*%T  
    E=$7ieW  
    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。 IiG4ib>)W

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K!pxDW}  
    1. 创建Matlab服务器。 ?IL! X-xx  
    2. 移动探测面对于前一聚焦面的位置。 y.L|rRe@P  
    3. 在探测面追迹光线 @hE7r-}]  
    4. 在探测面计算照度 B)_!F`9  
    5. 使用PutWorkspaceData发送照度数据到Matlab P c/.*kOT  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  "Nk`RsW  
    7. 用Matlab画出照度数据 ?FkQe~FN{  
    8. 在Matlab计算照度平均值 Lr!L}y9T+  
    9. 返回数据到FRED中 WiPM <'
