FRED案例-FRED如何调用Matlab
Db"DG( 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。 U=8@@yE v_<2H'*Q 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: )fdE6 enableservice('AutomationServer', true) Q o =Kqv enableservice('AutomationServer') "g+z !4b#
FecktD= 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。 ^h&I H| iBudmT8 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: |Oag,o" 1. 在FRED脚本编辑界面找到参考. Dr;iQkGP
2. 找到Matlab Automation Server Type Library xmGk*W)P 3. 将名字改为MLAPP h O

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。 US{3pkr;I] 图 编辑/参考 Npn=cLC& xLZd!>C gK|R =J 现在将脚本代码公布如下,此脚本执行如下几个步骤: 2l5KJlfj>k 1. 创建Matlab服务器。 [Vdz^_@Y 2. 移动探测面对于前一聚焦面的位置。 h8jD}9^ 3. 在探测面追迹光线 *V(Fn-6( 4. 在探测面计算照度 j8 C8X$ 5. 使用PutWorkspaceData发送照度数据到Matlab (c v!Y=] 6. 使用PutFullMatrix发送标量场数据到Matlab中 yg]2erR 7. 用Matlab画出照度数据 s=Q(C[%I 8. 在Matlab计算照度平均值 E2B>b[ 9. 返回数据到FRED中 @/%{15s.
