f+huhJS5e 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。
O=St}B\!m K_B-KK(^ 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:
$9\!CPZ2 enableservice('AutomationServer', true)
3say&|kJ enableservice('AutomationServer')
Y m|zM1qc
Ro?aDrQ 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。
e;<=aa)}? 9Qb_BNUo 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:
i4N'[ P} 1. 在FRED脚本编辑界面找到参考.
6nRD:CH)X 2. 找到Matlab Automation Server Type Library
i1?H*:] 3. 将名字改为MLAPP
]J C}il_b T?c:z?j_9 DxT8;`I% 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。

Xb=9~7&,$ 1. 创建Matlab服务器。
P-VK=Y1q 2. 移动探测面对于前一聚焦面的位置。
W9?Vh{w 3. 在探测面追迹
光线 [(Pm\o 4. 在探测面计算
照度 w7]@QTC 5. 使用PutWorkspaceData发送照度数据到Matlab
0t1WvW 6. 使用PutFullMatrix发送标量场数据到Matlab中
Z*QsDS 7. 用Matlab画出照度数据
4*_9Gl 8. 在Matlab计算照度平均值
@U(D&_H,K 9. 返回数据到FRED中
