w0x%7mg@ 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。
T jO}P\p =N,Mmz% 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:
Q:\I
%o enableservice('AutomationServer', true)
VJM n5v[V enableservice('AutomationServer')
S~+}_$
<_@ S@t) 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。
(]Z%&>* S1pikwB 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:
f1;Pzr 1. 在FRED脚本编辑界面找到参考.
X I\zEXO 2. 找到Matlab Automation Server Type Library
n&=3Knbd@d 3. 将名字改为MLAPP
L$7
NT}L +*3\C! -I.OvzQ* 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。

oc,a 3. 在探测面追迹
光线 QDS=M] 4. 在探测面计算
照度 0nS69tH 5. 使用PutWorkspaceData发送照度数据到Matlab
~Rx[~a 6. 使用PutFullMatrix发送标量场数据到Matlab中
dm1WC:b 7. 用Matlab画出照度数据
N3Ub|$}q 8. 在Matlab计算照度平均值
ajuwP1I 9. 返回数据到FRED中
