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。 !B|Aq-
n, zbY2gq@? 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: fab.%$ enableservice('AutomationServer', true) Jt++3] enableservice('AutomationServer') ?qC6p|H ^#( B4l! 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。 r+:]lO "%peYNZ&% 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: 5}C.^ J` 1. 在FRED脚本编辑界面找到参考. c!0u,6 2. 找到Matlab Automation Server Type Library z][hlDv\j 3. 将名字改为MLAPP .q90+9Ek= b!p]\B! {{6D4M|s 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。 \<ko)I#% %cO^: 图 编辑/参考 ES}V\k*} \1Xr4H
