=woP~+ 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。
5K-,k^T} .{|SKhXk 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:
YMVi7D~;Q$ enableservice('AutomationServer', true)
YL78cWOs enableservice('AutomationServer')
HTMg{_r(%
W|"bV 6d3 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。
5\h 6' vU(fd!V ? 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:
/1$u|Gs
* 1. 在FRED脚本编辑界面找到参考.
J%T=FU 2. 找到Matlab Automation Server Type Library
z?F`)} 3. 将名字改为MLAPP
f1sp6S0V\ 3Tp8t6*nL *`LrvE@t 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。

oOaLD{g> 1. 创建Matlab服务器。
D7muf 2. 移动探测面对于前一聚焦面的位置。
@(+\*]?^& 3. 在探测面追迹
光线 d_ x

照度 3to!C"~\K- 5. 使用PutWorkspaceData发送照度数据到Matlab
-yb7s2o 6. 使用PutFullMatrix发送标量场数据到Matlab中
/Ak\Q5O'3 7. 用Matlab画出照度数据
,H8M.hbsQ 8. 在Matlab计算照度平均值
#_UP}G$ 9. 返回数据到FRED中
