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。 ]2SF9p_ 0Rn+`UnwB 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: 63WS7s" enableservice('AutomationServer', true) \[:/CxP enableservice('AutomationServer') N5U)*U'-u /*)Tl 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。 (<*e .N m su+s 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: =<z.mzqu5 1. 在FRED脚本编辑界面找到参考. /s:fW+C 2. 找到Matlab Automation Server Type Library F_3:bX 3. 将名字改为MLAPP njPPztv/@ ^]C&tG0 ! ! ]`
#JAL7 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。 -Sv"gLB X|LxV] 图 编辑/参考 ksR1kvTm bO5k6i 现在将脚本代码公布如下,此脚本执行如下几个步骤: c:!z O\P# 1. 创建Matlab服务器。 ~ Hy,7 2. 移动探测面对于前一聚焦面的位置。 _Xcn
