FRED案例-FRED如何调用Matlab
RTlC]`IGT 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。 wzy[sB274 T`@brL 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,TApF89A enableservice('AutomationServer', true) MuWZf2C enableservice('AutomationServer') Y$v d@Q
,X3D<wl 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 _k]R6V: Y}BP]#1 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: +PE-j| D 1. 在FRED脚本编辑界面找到参考. ggPGKY-b= 2. 找到Matlab Automation Server Type Library O$, 3. 将名字改为MLAPP S}rEQGGR{ AQ$)JPs +i}H $.
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。 F1BvDplQ>G 图 编辑/参考 ~.x #ic 95IP_1}? 1/mBp+D 现在将脚本代码公布如下,此脚本执行如下几个步骤: w!<e#Z]3b 1. 创建Matlab服务器。 E8av/O
