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。 ?B&@
$|2@of. 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: t!g9,xG<X enableservice('AutomationServer', true) x*9CK8o= enableservice('AutomationServer') ^lP_{c wM^_pah#Y5 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 {c3u!}mW ;bZIj`D( 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 4l2xhx 1. 在FRED脚本编辑界面找到参考. as{^~8B 2. 找到Matlab Automation Server Type Library ||lI_B 3. 将名字改为MLAPP l[2 d{r nVTCbV _V9 O,"DDc 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 G2nL#l~@) qXGAlCq@ 图 编辑/参考 4@wH4H8 xz+Y 1fYT 现在将脚本代码公布如下,此脚本执行如下几个步骤: buXPeIo^VM 1. 创建Matlab服务器。 e$E~@{[1) 2. 移动探测面对于前一聚焦面的位置。 T/_JXK>W 3. 在探测面追迹光线 #>|l"1 4. 在探测面计算照度 Qr/8kWa0C 5. 使用PutWorkspaceData发送照度数据到Matlab z_dorDF8`> 6. 使用PutFullMatrix发送标量场数据到Matlab中 ',MiD=_ 7. 用Matlab画出照度数据 |vZ\tQ
