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。 w8Q<r. h"mi"H^o 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: z+}QZ> enableservice('AutomationServer', true) )m3Uar enableservice('AutomationServer') 8LkP)]4^sO wBj-m 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。 \2-@' ^i rHge~nY< 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: 4LcX<BU9 1. 在FRED脚本编辑界面找到参考. 1+;C`bnA 2. 找到Matlab Automation Server Type Library _Q%vK*n 3. 将名字改为MLAPP 8F(h*e_? }kHdK vZ Jq.lT(E8D 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。 w>fdQ!RdP -Y#sI3o*R8 图 编辑/参考 4BYE1fUzd `N//A}9 现在将脚本代码公布如下,此脚本执行如下几个步骤: TcTM]ixr 1. 创建Matlab服务器。 Cb t{H}I3 2. 移动探测面对于前一聚焦面的位置。 )4U>!KrY 3. 在探测面追迹光线 WF&[HKOy/ 4. 在探测面计算照度 gbeghLP[? 5. 使用PutWorkspaceData发送照度数据到Matlab
