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。 <7XT\?%F hoQ7).> 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: 2(M6(xH> enableservice('AutomationServer', true) XiQkrZ enableservice('AutomationServer') W3rl^M=r .lN s4e 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。 ;o-yQmdh +fNvNbtA 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: >cN~U3 1. 在FRED脚本编辑界面找到参考. *7$P] 2. 找到Matlab Automation Server Type Library / i_ @ 3. 将名字改为MLAPP P0Z!?`e=M /6+NU^ -#s [F 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。 L}sx<=8.m 8VQ 24r
