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。 E'iN==p_: HS@ EV iht 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: 4T??8J-J enableservice('AutomationServer', true) ~Iz{@Ep* enableservice('AutomationServer') VBq|j"o0" Em]2K: 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。 EC`=nGF 8$~^-_>n/ 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: ! lxq,Whr{ 1. 在FRED脚本编辑界面找到参考. p6AF16*f0 2. 找到Matlab Automation Server Type Library >`=9So_J 3. 将名字改为MLAPP y"T(Unvc pZ)N,O3 OSY.$$IO 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。 +aZcA#% K:L_y1!T 图 编辑/参考 `_+% E@/*eJ 现在将脚本代码公布如下,此脚本执行如下几个步骤: KbGz3O'u 1. 创建Matlab服务器。 OVUJiBp 2. 移动探测面对于前一聚焦面的位置。 ;km ^ OO$ 3. 在探测面追迹光线 sL4j@Lt 4. 在探测面计算照度 _@@.VmZL 5. 使用PutWorkspaceData发送照度数据到Matlab l>*L
