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。 <sE0426
{ "X=l7{c/ 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: t
5g@t0$ enableservice('AutomationServer', true) % V/J6 enableservice('AutomationServer')
3V>2N)3`A 9l5l"Wj& 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。 v `9IS+Z E`}KVi57 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: CXwDG_e 1. 在FRED脚本编辑界面找到参考. ,dOd3y'y 2. 找到Matlab Automation Server Type Library 9
N[k ?kUZ 3. 将名字改为MLAPP bsO78a~=P pn<M`,F~q 21_>|EKp 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。 A
