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。 U+
=q_ < g*M3;G
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: o+&sodt|` enableservice('AutomationServer', true) WgB,,L, enableservice('AutomationServer') |0-L08DW C@i g3fhV 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。 \O~7X0 <W Y~!@ 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: r_m&Jl@4 1. 在FRED脚本编辑界面找到参考. 3RUB2c4 2. 找到Matlab Automation Server Type Library PV2904 3. 将名字改为MLAPP ntejFy9_ m<4Lo0?nS FC#Qtu~J 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。 l ,.;dw ."O(Ig[ 图 编辑/参考 oP6G2@3P/ Kw|`y %~ 现在将脚本代码公布如下,此脚本执行如下几个步骤: }s[/b"%y 1. 创建Matlab服务器。 [>86i 2. 移动探测面对于前一聚焦面的位置。 m/AN*`V 3. 在探测面追迹光线 Wwz{98,K 4. 在探测面计算照度 VrK 5a9*^ 5. 使用PutWorkspaceData发送照度数据到Matlab G'Y|MCKz> 6. 使用PutFullMatrix发送标量场数据到Matlab中 Fz% n!d 7. 用Matlab画出照度数据 )LG/n 8. 在Matlab计算照度平均值 X(\RA.64 9. 返回数据到FRED中 S EmD's xT/&'$@{) 代码分享: .^23qCs mVLGQlvVK Option Explicit 3^Y-P8.zdB QZfnoKz Sub Main ?:E;C<Ar I(.XK ucU Dim ana As T_ANALYSIS P_gQ-pF.
