~ M"[FYw[ 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。
OygYP V3-LVgM% 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:
mb#)w`< enableservice('AutomationServer', true)
\ l:n enableservice('AutomationServer')
BdceINI
&I70veNY 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。
@U&|38 bx@CzXre; 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:
6x{B 1. 在FRED脚本编辑界面找到参考.
au8)G_A 2. 找到Matlab Automation Server Type Library
sU8D;ML7 3. 将名字改为MLAPP
h1BdASn_ NzEuiI} ScI9.{ 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。

照度 }SYvGp{J, 5. 使用PutWorkspaceData发送照度数据到Matlab
NZl0sX.: 6. 使用PutFullMatrix发送标量场数据到Matlab中
rlds-j'' 7. 用Matlab画出照度数据

JsH9IK: 9. 返回数据到FRED中
