FRED如何调用Matlab
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。 `g,i`< K55]W2I9 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: U$6(@&P! enableservice('AutomationServer', true) 2~W8tv0^b2 enableservice('AutomationServer') 95BRZ!ts
{'q(a4 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。 h[j(@P w?A6S-z 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: ,gn**E 1. 在FRED脚本编辑界面找到参考. &v&e-|r8; 2. 找到Matlab Automation Server Type Library 43o!Vr/S 3. 将名字改为MLAPP 9
IY1"j0O >I*uo.OF FK`M+ j 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。 JCZ 5q9b E'F87P ^>
