    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。 wWUt44:0O  
    Mhj.3nN  
    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: tcS7 @^'  
    enableservice('AutomationServer', true) U6R~aRJ;  
    enableservice('AutomationServer') b!-F!Lq/+0  
    .UJjB}4$f  
    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 srfM"Lb'  
    IgU65p  
    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: 0hx EI  
    1. 在FRED脚本编辑界面找到参考. <gc\ ,P<ru  
    2. 找到Matlab Automation Server Type Library M%Dv-D{  
    3. 将名字改为MLAPP h; 8^vB y  
    h4dT N}  
    mg7Q~SLL{  
    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。 FYu=e?L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: a8!/V@a  
    1. 创建Matlab服务器。 Yv[j5\:x  
    2. 移动探测面对于前一聚焦面的位置。 ^qlfdf  
    3. 在探测面追迹光线 an9k2 F.)  
    4. 在探测面计算照度 D%k]D/  
    5. 使用PutWorkspaceData发送照度数据到Matlab jI9Kn41  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ir*T ,O 2J  
    7. 用Matlab画出照度数据 atO/Tp  
    8. 在Matlab计算照度平均值 }28,fb /  
    9. 返回数据到FRED中 vg/:q>o
