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。 H]K(`)y}4 +K,]#$k 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: NitWIj[U; enableservice('AutomationServer', true) N
'2Nv enableservice('AutomationServer') V\r!H>

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。 &$ZJfHD@ 9ar+P h@* 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: gf7%vyMo$ 1. 在FRED脚本编辑界面找到参考. i7v> 9p7 2. 找到Matlab Automation Server Type Library #?-2f{ 3. 将名字改为MLAPP >xb}AY; 42kr&UY& q '9u8b 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。 :t+XW`eQR: tP8>0\$) 图 编辑/参考 i;>Yx# %H Pwu & 现在将脚本代码公布如下,此脚本执行如下几个步骤: b"n0Yk1 1. 创建Matlab服务器。 _0p8FhNt 2. 移动探测面对于前一聚焦面的位置。 4/e|N#1`;[ 3. 在探测面追迹光线 Q{1Q w'+@ 4. 在探测面计算照度 Ey7SQb 5. 使用PutWorkspaceData发送照度数据到Matlab &6V[@gmD
