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。 ?b^<Tny *X|%H-Q:H` 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: h;K9}w enableservice('AutomationServer', true) IMSm enableservice('AutomationServer') $3#oA.~R/ Jl"DMUy[kW 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 /KvpJ4 /$vX1T 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: Grd9yLF 1. 在FRED脚本编辑界面找到参考. `b@"GOr 2. 找到Matlab Automation Server Type Library N/^[c+J[E 3. 将名字改为MLAPP ?K}KSJ6_ P#A|Pn<p Dhg/>@tw 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。 )[sSCt] *OE>gg&?Nh 图 编辑/参考 dj0Du^v4 4P24ySy9F 现在将脚本代码公布如下,此脚本执行如下几个步骤: kr1^`>O5 1. 创建Matlab服务器。 Y u^ } 2. 移动探测面对于前一聚焦面的位置。 NX+
