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%W>m0% S59^$ 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: vr4{|5M enableservice('AutomationServer', true) d^8n enableservice('AutomationServer') hjz`0AS <B!DwMk;. 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。 piFZu/~Gq\ gOr%N!5 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: ;Kh?iqn^ 1. 在FRED脚本编辑界面找到参考. Y+eDE:4 2. 找到Matlab Automation Server Type Library ]U&<y8Q_6 3. 将名字改为MLAPP <8^ws90Y \46*4?pP K^IB1U$ 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。
