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。 ]n/fB|t E ;:0gN|+ 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: `U~Y{f_!H enableservice('AutomationServer', true) +ISXyGu enableservice('AutomationServer') -4}I02 Z
T5p 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。 nV$ctdusQ ":o1g5? 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: .W9/*cZV0 1. 在FRED脚本编辑界面找到参考. 4_A9o9&_Rh 2. 找到Matlab Automation Server Type Library ;4g_~fB 3. 将名字改为MLAPP l:Y$A$W]> |>Xw"]b; @|2}*_3\ 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。 S dI/ E\%'/3o 图 编辑/参考 f%1Dn }6 N%2UL&w#B 现在将脚本代码公布如下,此脚本执行如下几个步骤: +]!`> 1. 创建Matlab服务器。 1f.xZgO/2 2. 移动探测面对于前一聚焦面的位置。 $_.m< 3. 在探测面追迹光线 .QhH!#Y2D 4. 在探测面计算照度 l5jW`cl1 5. 使用PutWorkspaceData发送照度数据到Matlab R+s_uwS 6. 使用PutFullMatrix发送标量场数据到Matlab中 X>
