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。 R@#G>4 Bk\Gj`"7 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: k{$ ao enableservice('AutomationServer', true) 1`9xIm*9w enableservice('AutomationServer') |7pR)KH3 ?zJOh^ 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。 TkO[rAC v\"S

JiU9CeD3 2. 找到Matlab Automation Server Type Library WJ9cZL 3. 将名字改为MLAPP ~ Yngkt @*DyZB Q\,o:ZU_ 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。 OOz[-j>'Y+ PeE/iZ. 图 编辑/参考 3 Lsj}p rzI|?QaPi 现在将脚本代码公布如下,此脚本执行如下几个步骤: ulJX1I=|p 1. 创建Matlab服务器。 BMIyskl=i 2. 移动探测面对于前一聚焦面的位置。 5+jf/}tA 3. 在探测面追迹光线 "A)(" 4. 在探测面计算照度 =@5x"MOz 5. 使用PutWorkspaceData发送照度数据到Matlab $eBX 6. 使用PutFullMatrix发送标量场数据到Matlab中 ^Mk%z9
