n:'BN([]o 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。
({KAh? p^rX.?X 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:
vkpV,}H enableservice('AutomationServer', true)
g
u =fq\` enableservice('AutomationServer')
Ro]IE|Fv
0juIkN# 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。

K4/P(*r` 2{kfbm-89t L*01l"5 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。
