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。 OqtGKda !GOaBs 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: C% -Tw]T$_ enableservice('AutomationServer', true) @3`5(xwzm enableservice('AutomationServer') zlMh^+rMX sn"((BsO< 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 .*zN@y3 rr#nBhh8 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ~${~To8$CW 1. 在FRED脚本编辑界面找到参考. 161P%sGx2 2. 找到Matlab Automation Server Type Library i/:L^SQAq 3. 将名字改为MLAPP 4`O[U#? 2w|5SK_ WD5J2EePT 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。 zx@!8Z <83Ky;ry 图 编辑/参考 @*%3+9`yq kn3w6] 现在将脚本代码公布如下,此脚本执行如下几个步骤: Y?^liI`# 1. 创建Matlab服务器。 zgD?e?yPO 2. 移动探测面对于前一聚焦面的位置。 0/HFLz' 3. 在探测面追迹光线 $dM_uSt 4. 在探测面计算照度 FJ_JaIby 5. 使用PutWorkspaceData发送照度数据到Matlab 0CzQel)L: 6. 使用PutFullMatrix发送标量场数据到Matlab中 =O}I{dNKZV 7. 用Matlab画出照度数据 @CNJpQ ujn 8. 在Matlab计算照度平均值 Snr(<u 9. 返回数据到FRED中
