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。 OiB*,TWV sOc<'):TK 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: \3P.G S{l enableservice('AutomationServer', true) Vp = enableservice('AutomationServer') <8UqV.& ld~8g, 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。
:e-&,K eySV -f{ 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: hZ0p /Bdv 1. 在FRED脚本编辑界面找到参考. lO482l_t 2. 找到Matlab Automation Server Type Library yZf+*j/a7 3. 将名字改为MLAPP xrbDqA.b (mq 7{;7y =}S*]Me5 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。 65FdA-4 :Jp$_T&E 图 编辑/参考 NTRw:' Wsb=SM7; 现在将脚本代码公布如下,此脚本执行如下几个步骤: 0 S3~IeJ 1. 创建Matlab服务器。 :tP:X+?O 2. 移动探测面对于前一聚焦面的位置。 '}a[9v76 3. 在探测面追迹光线 ?!H<V@a 4. 在探测面计算照度 <v<TsEI 5. 使用PutWorkspaceData发送照度数据到Matlab 7
