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。 I:&/`K4,x, =d
2 r6%v 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: iq#b#PYA enableservice('AutomationServer', true) sRVIH A, enableservice('AutomationServer') 6\7ncFO3 BC>=B@H0 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。 |rw%FM{F z2gk[zY& 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: gbOpj3 1. 在FRED脚本编辑界面找到参考. gyHHoZc3 2. 找到Matlab Automation Server Type Library 'z@ 0 3. 将名字改为MLAPP 2Q7R6*<N: :%&Q-kk4! <oKGD50# 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。 "eWk#/ {U]H;~3 ? 图 编辑/参考 }UJv[ p?[Tm*r 现在将脚本代码公布如下,此脚本执行如下几个步骤: k-V,~c 1. 创建Matlab服务器。 l5%G'1w#,j 2. 移动探测面对于前一聚焦面的位置。 j| Wv7 3. 在探测面追迹光线 s..lK
