FRED案例-FRED如何调用Matlab
ESdjDg$[u 简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 4L'dV q cYF& 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: laVqI|0q enableservice('AutomationServer', true) *_Y{wNF* enableservice('AutomationServer') gJYB)LjH"
>l|ao&z>bm 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 sdkKvo.y0 o[C,fh,$ 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: O>P792) 1. 在FRED脚本编辑界面找到参考. Gn}G$uk61 2. 找到Matlab Automation Server Type Library KW^#DI6tr 3. 将名字改为MLAPP pwq a/Yi Hggp*(AQK ')ZM#
:G 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 ]w2nVC3 图 编辑/参考 !JZ)6mtlr 4.?tP7UE ivy+e-) 现在将脚本代码公布如下,此脚本执行如下几个步骤: ANuIPF4NxP 1. 创建Matlab服务器。 E+>$@STv# 2. 移动探测面对于前一聚焦面的位置。 K5;
