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。 GapX$Jb,p I{i:B 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: O>)n*OsS enableservice('AutomationServer', true) l}U~I
3}). enableservice('AutomationServer') FZeN, +9=@E 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 6qz!M ?qq!%4mTB 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: jQH5$ 1. 在FRED脚本编辑界面找到参考. w>/pQ6=OFR 2. 找到Matlab Automation Server Type Library $1Q3Y'Q9 3. 将名字改为MLAPP jSUAU}u!M ]4LT# a#OhWqu$ 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。 's56L,^: "-~D!{rS 图 编辑/参考 0+VncL)u ~T;ajvJ 现在将脚本代码公布如下,此脚本执行如下几个步骤: #*ZnA, 1. 创建Matlab服务器。 b.w(x*a 2. 移动探测面对于前一聚焦面的位置。 pw(U< ) 3. 在探测面追迹光线 Vsm%h^]d 4. 在探测面计算照度 os"[Iji 5. 使用PutWorkspaceData发送照度数据到Matlab Jq$6$A,f 6. 使用PutFullMatrix发送标量场数据到Matlab中 79<9}<T 7. 用Matlab画出照度数据 |}]JWsuB 8. 在Matlab计算照度平均值 g4.'T51 9. 返回数据到FRED中 w<I5@)i| 4N%2w(,+8 代码分享: \$$b",2
