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。 hn@08t G tcI*a> 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: Dz/ "M= enableservice('AutomationServer', true) 7n<{tM enableservice('AutomationServer') p]TAELy 7JH6A'& 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。 _V6ukd"B~ C,r;VyW6BI 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: C&%_a~ 1. 在FRED脚本编辑界面找到参考. bI1N@= 2. 找到Matlab Automation Server Type Library tyFzSrfc 3. 将名字改为MLAPP 0{D'n@veP #;yZ n_A3#d<9 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。 gwMNYMI 6H$FhJF 图 编辑/参考 lL3U8}vn ?:q*(EC< 现在将脚本代码公布如下,此脚本执行如下几个步骤: q0vQa 1. 创建Matlab服务器。 {EQOP] 2. 移动探测面对于前一聚焦面的位置。 CD~.z7,LC 3. 在探测面追迹光线 Vc Z3
