zn=Ifz)#| 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。
K] 5vfzSJ 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:
WPN4mEow enableservice('AutomationServer', true)
>l!#_a enableservice('AutomationServer')
h.~:UR*
O@Ro_sPG( 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。
b `7vWyp V\!6K 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:
0G=bu5 1. 在FRED脚本编辑界面找到参考.
KliMw*5( 2. 找到Matlab Automation Server Type Library
" 0:&x
n8L 3. 将名字改为MLAPP
CXe2G5 tJ_6dH8Y N>+s8L.? 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。

us_o{ 2. 移动探测面对于前一聚焦面的位置。
T[z}^" 3. 在探测面追迹
光线 LhfI"fc 4. 在探测面计算
照度 XVlZ:kz 5. 使用PutWorkspaceData发送照度数据到Matlab
oC~8h8"l 6. 使用PutFullMatrix发送标量场数据到Matlab中
MKnG:)T<?l 7. 用Matlab画出照度数据
<#[_S$54 8. 在Matlab计算照度平均值
#lf3$Tm D 9. 返回数据到FRED中
