    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。 QM F   
    k?14'X*7yu  
    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: 3NtUB;!  
    enableservice('AutomationServer', true) O`9c!_lis  
    enableservice('AutomationServer') &bW,N  
    aX^T[  
    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 FKTF?4+\U  
    Nv7-6C6<  
    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: yx5e  
    1. 在FRED脚本编辑界面找到参考. -!Myw&*\V  
    2. 找到Matlab Automation Server Type Library %hsCB .r>|  
    3. 将名字改为MLAPP e4tIO

    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。 ,r~+ 9i0N

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Reikf}9Q  
    1. 创建Matlab服务器。 y ("WnVI  
    2. 移动探测面对于前一聚焦面的位置。 Q?k *3A  
    3. 在探测面追迹光线 V:kRr cX  
    4. 在探测面计算照度 f1MRmp-f'  
    5. 使用PutWorkspaceData发送照度数据到Matlab \b"rf697 ,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 m}uOBR+  
    7. 用Matlab画出照度数据 =\oH= f  
    8. 在Matlab计算照度平均值 Af;Pl|Zh[  
    9. 返回数据到FRED中 eBrNhE-[G]
