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。 D =mmBo #Tei0B7 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: 4>i\r enableservice('AutomationServer', true) &3Yj2Fw enableservice('AutomationServer') l cHf\~ "~0`4lo:Xo 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。 2.I|8d[ }oA>0Nw$K 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Jw8?o/1D@ 1. 在FRED脚本编辑界面找到参考. nj:w1E/R 2. 找到Matlab Automation Server Type Library tE_n>~Zs 3. 将名字改为MLAPP >5#}/G& Yj1|]i5b xYCJO(& 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 [#mkTY ^h$*7u"^y 图 编辑/参考 w~)tEN> $BMXjXd} 现在将脚本代码公布如下,此脚本执行如下几个步骤: iuGwc086 1. 创建Matlab服务器。 s{R,- \_ 2. 移动探测面对于前一聚焦面的位置。 n)"JMzjQ< 3. 在探测面追迹光线 \OtreYi 4. 在探测面计算照度 c0'ryS_Z9 5. 使用PutWorkspaceData发送照度数据到Matlab 0t%]z! 6. 使用PutFullMatrix发送标量场数据到Matlab中 j
