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。 %g4G&My@J H`;q@ 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: Jtxwt[ enableservice('AutomationServer', true) F+!K9( `| enableservice('AutomationServer') ga~C?H,K
g2v0! 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。 Gt^Fj&^ 0XBv8fg 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: -%lA=pS{Fq 1. 在FRED脚本编辑界面找到参考. ;X

% 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。 O!(M:. B#_<?
