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。 %^C.e* n!*uv~%$ 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: 8%;K#,> enableservice('AutomationServer', true) 53w@ enableservice('AutomationServer') EC6Q<&]Iw e~wJO~ 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。 @^)aUOe i47xF7y\ 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: 4[eQ5$CB<u 1. 在FRED脚本编辑界面找到参考. %%w/;o!c 2. 找到Matlab Automation Server Type Library z U~o"Jv 3. 将名字改为MLAPP Y^(Sc4 W R1%2]? fzVU9BU 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。 3Q@HP;< vj23j[!| 图 编辑/参考 ,z1fiq guC7!P^ 现在将脚本代码公布如下,此脚本执行如下几个步骤: _E{hB 1. 创建Matlab服务器。 D3>;X= 1 2. 移动探测面对于前一聚焦面的位置。 %!>~2=Q2* 3. 在探测面追迹光线 $YyN-C 4. 在探测面计算照度 2+Tu"oG;rB 5. 使用PutWorkspaceData发送照度数据到Matlab nnZ|oEF 6. 使用PutFullMatrix发送标量场数据到Matlab中 DjX*2O 7. 用Matlab画出照度数据 ^.d97rSm 8. 在Matlab计算照度平均值 7fOk]Yl[ 9. 返回数据到FRED中 JBsHr%!i mu(EmAoenQ 代码分享: e[lRY>Pe5 $6c8<!B_ Option Explicit Z{|U!tn BK_x5mGu3 Sub Main INyakAmJ}- y'9
