r.[9/'> 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。
M5wj79'l" WUKYwA/t 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:
O3Yv -># enableservice('AutomationServer', true)
60Y&)UR enableservice('AutomationServer')
66v6do7
JBp^@j{_ 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。
OX I.>9 q45Hmz 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:
sk9*3d5I 1. 在FRED脚本编辑界面找到参考.
WJ8i,7 2. 找到Matlab Automation Server Type Library
<yBZsSj 3. 将名字改为MLAPP
$`mxOcBmQ Ao(Xz$cQfW [*@"[u 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。

J&wrBVv1uk 1. 创建Matlab服务器。
iCnKQG 2. 移动探测面对于前一聚焦面的位置。
LGV"WE 3. 在探测面追迹
光线 V |)3l7IC< 4. 在探测面计算
照度 l@%MS\{ 5. 使用PutWorkspaceData发送照度数据到Matlab
-b8Vz}Y 6. 使用PutFullMatrix发送标量场数据到Matlab中
]:d`=V\&N 7. 用Matlab画出照度数据
m!V ?xGKJ 8. 在Matlab计算照度平均值
o/
ozX4C 9. 返回数据到FRED中
