/: }"Z b 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。
sy+tLDMd gO]jeO 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:
r=^? enableservice('AutomationServer', true)
+m1y#|08 enableservice('AutomationServer')
\9jvQV/y
%b3s|o3An 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。

Q2[ >Byxb./* 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:
