m8<l2O=m 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。
A>W8^|l6+- x9VR>ux& 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:
^K
n{L enableservice('AutomationServer', true)
%oqC5O6 enableservice('AutomationServer')
;]xJC
j
khtYn.eaL 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。
([L5i&DT \-~TW4dYe 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:
&Ew{ {t;" 1. 在FRED脚本编辑界面找到参考.
