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。 }C9VTJs| z0FR33- 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: =aX1:Z enableservice('AutomationServer', true) w/)e2CH enableservice('AutomationServer') k|)^!BdO n/,rn>k7: 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。 Ss*LgK_ ,=x.aX
Spz 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: `XFX`1 1. 在FRED脚本编辑界面找到参考. $u(M 4(} 2. 找到Matlab Automation Server Type Library _%C_uBLi 3. 将名字改为MLAPP [0(
E>vm +sV# Z, il 8A&`% 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。 x|P<F 2L C"V?yDy2~ 图 编辑/参考 n:{-Vvt |~1rKzZwF
