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。 fzw6VGTf # Dy;x\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: N8m^h:b enableservice('AutomationServer', true) } |sP;Rpu enableservice('AutomationServer') PJb_QL!9 ~tz[=3!1H 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。 AbfLV942 {uw'7 d/ 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: ~1}NQa( 1. 在FRED脚本编辑界面找到参考. #%+IU 2. 找到Matlab Automation Server Type Library I80.|KIv 3. 将名字改为MLAPP qjTz]'^BpM ! 4i X'iki4 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。 sPbtv[bC cZ o]*Gv. 图 编辑/参考 [S$)^>0 spFsrB 现在将脚本代码公布如下,此脚本执行如下几个步骤: %L~X\M:Qk 1. 创建Matlab服务器。 Lw-j#}&6E 2. 移动探测面对于前一聚焦面的位置。 S:
