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。 sqP (1|9 wSd o7Lb 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: jj8h>"d enableservice('AutomationServer', true) 2/ v9 enableservice('AutomationServer') 6
s1lf! yp.\KLq8) 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。 #gd`X|<Ch wJKP=$6n_ 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: y?*4SLy 1. 在FRED脚本编辑界面找到参考. |Wzdu2T 2. 找到Matlab Automation Server Type Library f=/IwMpn 3. 将名字改为MLAPP f hS4Gb_ -OPJB:7Z
*aT\V64 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。 fkmN?CU{1% zs@xw@
