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。 dGt;t5AnV 1\z5[
_ 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: 0UB)FK,9 enableservice('AutomationServer', true) luACdC enableservice('AutomationServer') n2zJ' &|'1.^f@;E 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。 5D8V)i Wz)s# 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: mY*JNx 1. 在FRED脚本编辑界面找到参考.

lZ 3. 将名字改为MLAPP zlco?Rt F.i*'x0u `wj<d>m 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。
