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。 /;zZnF\e 5wT',U"+ 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: 7^n,Tig enableservice('AutomationServer', true) Z'voCWCd enableservice('AutomationServer') |3s.;wK 7yo|ie@S 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。 C}x4#bNK ^nG1/} 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: QWU5-p9e8 1. 在FRED脚本编辑界面找到参考. hdo+Qezu: 2. 找到Matlab Automation Server Type Library pA*D/P- 3. 将名字改为MLAPP ;:v]NZtc d,Hf-zJ%~ HY*l 4QK 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。 ~,(0h:8 \W3+VG2cA 图 编辑/参考 h<PYE]?l Yt\E/*% 现在将脚本代码公布如下,此脚本执行如下几个步骤: 6^7)GCq [ 1. 创建Matlab服务器。 P58\+9d_ 2. 移动探测面对于前一聚焦面的位置。 9nP*N` 3. 在探测面追迹光线 M>`?m
