f1>^kl3@P 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。
J0|}u1?l %jM|*^\% 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:
XT_BiZ%l5O enableservice('AutomationServer', true)
cw <DM%p enableservice('AutomationServer')
bvR*sT#rg
fhn0^Qc"+ 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。
RN:#+S(8 I.e' 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:
[%nG_np 1. 在FRED脚本编辑界面找到参考.
L ou4M 2. 找到Matlab Automation Server Type Library
{nOK*7+" 3. 将名字改为MLAPP
[I4FU7mpH I}v'n{5( L{fP_DIa 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。

0XYO2k 1. 创建Matlab服务器。
rrwsj` 2. 移动探测面对于前一聚焦面的位置。
3Ob"r` 3. 在探测面追迹
光线 j*:pW;)^ 4. 在探测面计算
照度 kdYl>M 5. 使用PutWorkspaceData发送照度数据到Matlab
UXk8nH 6. 使用PutFullMatrix发送标量场数据到Matlab中
5!ReW39c; 7. 用Matlab画出照度数据
47K5[R 8. 在Matlab计算照度平均值
dju&Ku
9. 返回数据到FRED中
