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。 q&NXF( w~pe?j_F$ 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:
rf'A+q enableservice('AutomationServer', true) w}(pc}^U enableservice('AutomationServer') )$a6l8
Fe$o*r, 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。 0(Z:QqpU$ /P46k4M1U 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: Nr)DU.f 1. 在FRED脚本编辑界面找到参考. `fJ;4$4 2. 找到Matlab Automation Server Type Library 0Ny +NE:6M 3. 将名字改为MLAPP on5\rY<I:@ DR]oK_ $rbr&TJ 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 KiE'O{Y v6! `H 图 编辑/参考 Hv:~)h$ #(a ;w 现在将脚本代码公布如下,此脚本执行如下几个步骤: ?
