x(`$D 简介:
FRED作为COM组件可以实现与Excel、VB、
Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。
-(.7/G'Vk> aiHr2x6 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
GP$Y4*y/ enableservice('AutomationServer', true)
OKVYpf enableservice('AutomationServer')
k
))*z FV
%np#Bv-L 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。
ar|[D7Xrq\ DE ws+y-* 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:
Anv8)J!9u 1. 在FRED脚本编辑界面找到参考.
OpLSjr 2. 找到Matlab Automation Server Type Library
nS4S[|w" 3. 将名字改为MLAPP
8tMte!E 02[II_< 1 )mdNvb[*n 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 _vH!0@QFU 4. 在探测面计算
照度 !@{[I:5 5. 使用PutWorkspaceData发送照度数据到Matlab
3L?a4,Q"k} 6. 使用PutFullMatrix发送标量场数据到Matlab中
a7\L-T+ 7. 用Matlab画出照度数据
C4tl4df9 8. 在Matlab计算照度平均值
M[u3]dN 9. 返回数据到FRED中
