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。 Y-a ~EPVu 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: lt&(S) enableservice('AutomationServer', true) P$#: $U@ enableservice('AutomationServer') 1d<Uwb> 3>aEP5 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 XAU%B-l: g=56|G7n 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: gYc]z5` 1. 在FRED脚本编辑界面找到参考. -PE_q Z^ 2. 找到Matlab Automation Server Type Library ?!U[~Gq 3. 将名字改为MLAPP ]$[sfPKA S-7&$n nOGTeKjEJ 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。 Ptv'.<- '%QCNO/ 图 编辑/参考 Ec@n<KK# p2i?)+z 现在将脚本代码公布如下,此脚本执行如下几个步骤: 73D<wMgZF 1. 创建Matlab服务器。 Lz'VQO1U= 2. 移动探测面对于前一聚焦面的位置。 '|zrzU= 3. 在探测面追迹光线 *{DTxEy 4. 在探测面计算照度 ^Fco'nlM 5. 使用PutWorkspaceData发送照度数据到Matlab Y#ZgrziYM 6. 使用PutFullMatrix发送标量场数据到Matlab中 Zp9.
