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。 RTYhgq uX,ln(9I*H 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: 5?MKx!% enableservice('AutomationServer', true) OSCe TkR enableservice('AutomationServer') :sekMNM V,
e 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。 b.v^:M zC$(/nZ
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: q*{Dy1Tj 1. 在FRED脚本编辑界面找到参考. b %I2ig 2. 找到Matlab Automation Server Type Library d#nKTqSg 3. 将名字改为MLAPP &M+fb4:_ %D*yXNsY %-[U;pJe; 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 4K$d% Psu*t%nQ?A 图 编辑/参考 z,=k F I iLG~_Ob: 现在将脚本代码公布如下,此脚本执行如下几个步骤: o*|j}hnbv 1. 创建Matlab服务器。 Qtn%h:i
