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。 "!+gA& n,U?]mr 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: p8Z?R^$9H enableservice('AutomationServer', true) sYjhQN=Y* enableservice('AutomationServer') w4(L@1 *Nm$b+ 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。 U0gZf5;* &&nbdu 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: SQ_Je+X 1. 在FRED脚本编辑界面找到参考. pO_IUkt 2. 找到Matlab Automation Server Type Library #x;,RPw5 3. 将名字改为MLAPP wA\5-C7j ;z.L^V0 SE'!j]6jI 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。 (:aU"5M 6<2H 7' 图 编辑/参考 D"J',YN$ %xN${4)6 现在将脚本代码公布如下,此脚本执行如下几个步骤: T'9ZR,{F 1. 创建Matlab服务器。 Y=p!xr> 2. 移动探测面对于前一聚焦面的位置。 >))CXGE 3. 在探测面追迹光线 ki?h7 4. 在探测面计算照度 y~fKLIoz" 5. 使用PutWorkspaceData发送照度数据到Matlab 4vEP\E3u<j 6. 使用PutFullMatrix发送标量场数据到Matlab中 hTa(^ 7. 用Matlab画出照度数据 V\o7KF 8. 在Matlab计算照度平均值 zw['hqW 9. 返回数据到FRED中 <
