AS'R?aX|C 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。
=9O^p@Q#W (C-{B[Y 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:
)t0$qd ] enableservice('AutomationServer', true)
n'wU;!W9 enableservice('AutomationServer')
,Ys %:>?
+%T\`6 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。
NO "xL, [YF>:ydk 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:
g]<4&)~ 1. 在FRED脚本编辑界面找到参考.
I5 o)_nc 2. 找到Matlab Automation Server Type Library
+7D|4 3. 将名字改为MLAPP
fHE<( E4`N-3 Se:.4< 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 .0S~872 5. 使用PutWorkspaceData发送照度数据到Matlab
f=(?JT 6. 使用PutFullMatrix发送标量场数据到Matlab中
