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。 ~YIGOL"? Tl#Jf3XY} 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: +s6wF{ enableservice('AutomationServer', true) ."m6zq enableservice('AutomationServer') !;SpQ28 eQk ~YA]K 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。 ub"(,k P zS Yh ?NB5 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: ZCQ7xQD 1. 在FRED脚本编辑界面找到参考. JJnZbJti 2. 找到Matlab Automation Server Type Library D_6GzgZ 3. 将名字改为MLAPP v-85`h Nxu10 L3Leb%,! 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。 n6gYZd B|IQ/g? 图 编辑/参考 k'N `5M) 9Z0(e!b4S 现在将脚本代码公布如下,此脚本执行如下几个步骤: U*ZP>Vv 1. 创建Matlab服务器。
