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。 $2N)m:X0 H]2cw{2 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: q))rlMo enableservice('AutomationServer', true) vU(2[ enableservice('AutomationServer') X}Heaqn ^)|8N44O 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 iOk^RDG+ eiE36+'>b 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 8bT]Nv CA 1. 在FRED脚本编辑界面找到参考. v%8.o%G 2. 找到Matlab Automation Server Type Library _?Q0yVH;, 3. 将名字改为MLAPP @T>\pP]o (/6~*<ZGT imGg3' 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 aYc*v5QN3 >drG,v0qh 图 编辑/参考 Xtv^q>! vhe[:`=a 现在将脚本代码公布如下,此脚本执行如下几个步骤: :5`=9_| 1. 创建Matlab服务器。 !>gi9z, 2. 移动探测面对于前一聚焦面的位置。 K1i@.`na/$ 3. 在探测面追迹光线 t2V|moG
