    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。 Zj nWbnW  
    ork{a.1-_w  
    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: X0KUnxw  
    enableservice('AutomationServer', true) a$LoQ<f_  
    enableservice('AutomationServer') YIYuqtnSJ  
    6p 14BruV  
    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 wJ7Fnj>u%  
    =e6!U5 f  
    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: v/`#Gu^P  
    1. 在FRED脚本编辑界面找到参考. G2J4N2hu  
    2. 找到Matlab Automation Server Type Library v\XO?UEJ2  
    3. 将名字改为MLAPP L_IvR 4:j~  
    B^x}=Z4

    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。 f{'N O`G

    现在将脚本代码公布如下,此脚本执行如下几个步骤: QwI HEmdM  
    1. 创建Matlab服务器。 a & 6-QVk  
    2. 移动探测面对于前一聚焦面的位置。 /j(<rz"j  
    3. 在探测面追迹光线 A{52T]9X  
    4. 在探测面计算照度  V#+J4   
    5. 使用PutWorkspaceData发送照度数据到Matlab C7Hgzc|U  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Vb~;"WABo  
    7. 用Matlab画出照度数据 PS??wlp7  
    8. 在Matlab计算照度平均值 ) KYU[  
    9. 返回数据到FRED中 77G4E ,]
