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)
F_E I 9:P)@UF 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: cu
Nwv(P enableservice('AutomationServer', true) } nQHP4' enableservice('AutomationServer') 6A%Y/oU+2 .EI/0"^ 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。 $T1c{T6n} Th-zMQ4 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: ;m\E9ple 1. 在FRED脚本编辑界面找到参考. {r Gx*<e 2. 找到Matlab Automation Server Type Library (bXCc 3. 将名字改为MLAPP 5ewQjwW0 <)M?qkjb 2WKA] l; 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。 k|w6&k3 >~6
