MuXp*s3[ 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。
m ;-FP 2~ CXt9 5O? 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:
hhd%j6 enableservice('AutomationServer', true)
+GCN63nX enableservice('AutomationServer')
O b'B?
y4*i
V;" 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。
su;u_rc, U-Ia$b-5! 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
-^sW{s0Rc 1. 在FRED脚本编辑界面找到参考.
X[/>{rK 2. 找到Matlab Automation Server Type Library
rk$&sDc/3 3. 将名字改为MLAPP
xxjg)rVuy )_bc:6Q -e<d//> 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 \f| Hk*@ 5. 使用PutWorkspaceData发送照度数据到Matlab
U%%fKL=S 6. 使用PutFullMatrix发送标量场数据到Matlab中
