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。 A2$05a$% z[y 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: }daU/ enableservice('AutomationServer', true) 0
ZSn r+ enableservice('AutomationServer') =ADOf_n} YOUB%N9+ 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。 OL_jU2,fv :zNNtv iA 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: :}-?X\|\ 1. 在FRED脚本编辑界面找到参考. mu5r4W47 2. 找到Matlab Automation Server Type Library O 0$V+fE 3. 将名字改为MLAPP q([{WZ:6Oq >?6HUUQ }6=?
zs} 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。 #%w)w R3 Z]x6np 图 编辑/参考 1g j GaC ~O]{m,)n 现在将脚本代码公布如下,此脚本执行如下几个步骤: ?'tRu !~ 1. 创建Matlab服务器。 Kmw #Q` 2. 移动探测面对于前一聚焦面的位置。 ap2g^lQXq 3. 在探测面追迹光线 z4;@"B 4. 在探测面计算照度 p}5413z5Z= 5. 使用PutWorkspaceData发送照度数据到Matlab L\t_zf_0 6. 使用PutFullMatrix发送标量场数据到Matlab中 |o'r?" 7. 用Matlab画出照度数据 j(k}NWPH 8. 在Matlab计算照度平均值 ) .KMZ] 9. 返回数据到FRED中 p#_5w Zo
