`c :'il? 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。
w2+RX-6Ie P2`ks[u+i 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:
hXz"}X n enableservice('AutomationServer', true)
lz{>c.Ll[ enableservice('AutomationServer')
KO)<Zh
Wv=L_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。
*zX<`E O])/kS` 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:
JYv&I t 1. 在FRED脚本编辑界面找到参考.
f\r$T Nd6 2. 找到Matlab Automation Server Type Library
A:
0]
n 3. 将名字改为MLAPP
{E 6W]Mno oC4rL\d{ U-WrZ|- 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。

光线 y:2o-SJn 4. 在探测面计算
照度 B5I(ai7<M 5. 使用PutWorkspaceData发送照度数据到Matlab
(/@o7&>*50 6. 使用PutFullMatrix发送标量场数据到Matlab中
R`1$z8$ 7. 用Matlab画出照度数据
L {B#x@9tQ 8. 在Matlab计算照度平均值
