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。 K>r,(zgVc +]A:M6P:{v 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: _A5e{Gb enableservice('AutomationServer', true) ?{|q5n enableservice('AutomationServer') LX7FaW zRl3KjET 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。 THbh%)Zv+ %C'?@,7C 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: K{cD+=]{ 1. 在FRED脚本编辑界面找到参考. ox>^>wR* 2. 找到Matlab Automation Server Type Library c~$)UND^ 3. 将名字改为MLAPP 5uNJx5g uK#4(eY=W .TR9975 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。 KRLQ #,9 " 4K(jXq| 图 编辑/参考 $L>@Ed< 2LL'J7 现在将脚本代码公布如下,此脚本执行如下几个步骤: |`f$tj 1. 创建Matlab服务器。 6C^
