FRED案例-FRED如何调用Matlab
!tFU9Zt 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。 E#HU?<q8 i5~ /+~ 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: mG8 enableservice('AutomationServer', true) >FMT#x t enableservice('AutomationServer') xzGsfd
* v7& T 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。 :xUl+(+ t2-zJJf8 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: OD@@O9 1. 在FRED脚本编辑界面找到参考. iR}i42Cu 2. 找到Matlab Automation Server Type Library iHG:W wM & 3. 将名字改为MLAPP X-2S*L' kvO`]>#;$? smLDm 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 |yl0}.() 图 编辑/参考 li'1RKr Z@aL"@2]a J'Mgj$T $ 现在将脚本代码公布如下,此脚本执行如下几个步骤: ^>R| R1& 1. 创建Matlab服务器。 KlX |PQ 2. 移动探测面对于前一聚焦面的位置。 S
