B<99-7x3 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。
%j.B/U$ 1Mf tq4nq 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:
Oy,7>vWQI enableservice('AutomationServer', true)
S,ENbP%0r enableservice('AutomationServer')
kM0TQX)$m
Ft&ARTsa* 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。
[MQU~+] +f}u.T_# 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:
4"om;+\ 1. 在FRED脚本编辑界面找到参考.
DRDn;j 2. 找到Matlab Automation Server Type Library
G^G= .9O 3. 将名字改为MLAPP
-`I&hzl6E Y#VtZTcT x1@`\r#0 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。
