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。 Cg pT(E\E CDnz
&? 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: KVxb"|[ enableservice('AutomationServer', true) % Au$E&sj enableservice('AutomationServer') % VpBB ~qxXou,J 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。 ?4e6w l-}5@D[ 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: z \>X[yNpA 1. 在FRED脚本编辑界面找到参考. $?AA"Nz 2. 找到Matlab Automation Server Type Library @T1+b"TC 3. 将名字改为MLAPP ]31XX= 9ox|.68q h;qy5KS 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。 e8mbEC(AK uhB!k-ir 图 编辑/参考 {@__%=`CCS @jSbMI 现在将脚本代码公布如下,此脚本执行如下几个步骤: %aBJ+V F 1. 创建Matlab服务器。 Tw;qY 2. 移动探测面对于前一聚焦面的位置。 3DC%I79 3. 在探测面追迹光线 VHr7GAmU 4. 在探测面计算照度 9zYiG3 d 5. 使用PutWorkspaceData发送照度数据到Matlab QhQ"OVFr# 6. 使用PutFullMatrix发送标量场数据到Matlab中 9+
