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。 4#_$@ r |:N>8%@6c 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 u"yAR enableservice('AutomationServer', true) x~EKGoz3 enableservice('AutomationServer') )yrAov\z* Pr`s0J%m 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。 S.W^7Ap F?cq'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: BRa{\R^I 1. 在FRED脚本编辑界面找到参考. h8jB=e, H 2. 找到Matlab Automation Server Type Library SRItE\"Xe 3. 将名字改为MLAPP =e{.yggE TY~Vi OC )&,K94
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。 ETO$9}x[ 4%J|D cY2 图 编辑/参考 g_vm&~U/' 3 z=\.R 现在将脚本代码公布如下,此脚本执行如下几个步骤: j=9ze op
