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。 VP!4Nob mX>N1zAz 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: Xm# +Z`|N enableservice('AutomationServer', true) jTS8
qu enableservice('AutomationServer') *C55DO^w oLkzLJ 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。 ?$`kT..j,u 2|"D\N 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: %f CkR`: 1. 在FRED脚本编辑界面找到参考. 53hX%{3 2. 找到Matlab Automation Server Type Library r0nnmy]{d 3. 将名字改为MLAPP S0StC$$1 /,SVG1 zHKP$k8 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。 1Xi>&;], jOCV)V9} 图 编辑/参考 9qDM0'WuU &w9*pJR % 现在将脚本代码公布如下,此脚本执行如下几个步骤: aEzf*a|fSV 1. 创建Matlab服务器。 ]Sj;\Iz 2. 移动探测面对于前一聚焦面的位置。 )@9Eq|jMC 3. 在探测面追迹光线 E-1u_7 4. 在探测面计算照度 RL&0?OT 5. 使用PutWorkspaceData发送照度数据到Matlab }bRn&)e 6. 使用PutFullMatrix发送标量场数据到Matlab中 K bQXH!J 7. 用Matlab画出照度数据 z
