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。 )CEfG IU/dY`J1 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: b6Dve] enableservice('AutomationServer', true) gHA"O@HgDI enableservice('AutomationServer') T/uj5pMG $^}?98m 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。 r#3(;N{= k)dLJ<EM 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: vt@.fT#e 1. 在FRED脚本编辑界面找到参考. KK}^E_v 2. 找到Matlab Automation Server Type Library X.bNU 3. 将名字改为MLAPP LEWeybT $_% a=0 -T`rk~A9A 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 0vt?yD &8z`]mB{t 图 编辑/参考 t|%wVj?_ !z$.Jcr1 现在将脚本代码公布如下,此脚本执行如下几个步骤: $9j\sZj& 1. 创建Matlab服务器。 x{j|Tf3,G 2. 移动探测面对于前一聚焦面的位置。 Kbrb;r59 3. 在探测面追迹光线 9v8{JaI3 4. 在探测面计算照度 p,Qr9p3y 5. 使用PutWorkspaceData发送照度数据到Matlab 8|OsVIe% 6. 使用PutFullMatrix发送标量场数据到Matlab中 ^ [uA^ 7. 用Matlab画出照度数据 yk,o*g 8. 在Matlab计算照度平均值 U;Y{=07a@ 9. 返回数据到FRED中 I!|_C~I` 2 S{zi8Oc6 代码分享: aI{Ehbf= 6DD"Asi+ Option Explicit #Huvn4x MOKg[j Sub Main I>B-[QEC GBFYa6\4sT Dim ana As T_ANALYSIS #;#
