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。 7=yV8.cD A.nU8 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: F)dJws7- enableservice('AutomationServer', true) =+24jHs enableservice('AutomationServer') :l~^un|<2Y S8-3Nv' 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。 ;tK%Q~To H+Dv-*i 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: !,8jB( 1. 在FRED脚本编辑界面找到参考. $80TRB# 2. 找到Matlab Automation Server Type Library QN`K|,}H^ 3. 将名字改为MLAPP 2JY]$$K7 9z>I&vcX hgt@Mb 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。 8nCw1 wuRB[KLe 图 编辑/参考 g}(yq:D ^e*Tg& 现在将脚本代码公布如下,此脚本执行如下几个步骤: MR$R# 1. 创建Matlab服务器。 ko-| hBNv 2. 移动探测面对于前一聚焦面的位置。 FKhmg&+> 3. 在探测面追迹光线 7K"{}: 4. 在探测面计算照度 -!d'!;
