FRED如何调用Matlab
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。 ;$]R#1i44 V qf}(3K0 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: oT w1w enableservice('AutomationServer', true) FS[CUoA enableservice('AutomationServer') EBm\rM8
xi0&"?7la 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。 ezeGw?/
NDi@x"]; 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: h#>67gJV 1. 在FRED脚本编辑界面找到参考. e^fjla5 2. 找到Matlab Automation Server Type Library h 9/68Gc?6 3. 将名字改为MLAPP 3? "GH1e Z1zC@z4sUj MwZ`NH|n3" 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。 <?eZ9eB a<Ta *:R$0
