    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。 O&1p2!Bk4  
    6 v#sq  
    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: 7VD7di=D  
    enableservice('AutomationServer', true) k$m X81  
    enableservice('AutomationServer') 0R{R=r]  
    kxiyF$ 9  
    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 +c2>j8e6

    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: Gf$>!zXr  
    1. 在FRED脚本编辑界面找到参考. S 2` ;7  
    2. 找到Matlab Automation Server Type Library V'#u_`x"D)  
    3. 将名字改为MLAPP cnO4N UDv  
    o ieLh"$  
    'r3}=z4Y  
    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]vBr^kq

    现在将脚本代码公布如下,此脚本执行如下几个步骤: v\T1,Z@N^  
    1. 创建Matlab服务器。 n_ gB#L$  
    2. 移动探测面对于前一聚焦面的位置。 @)Y7GM+^  
    3. 在探测面追迹光线 k0=y_7 =(5  
    4. 在探测面计算照度 "s^@PzQpN  
    5. 使用PutWorkspaceData发送照度数据到Matlab */qc%!YV9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y(g Otg  
    7. 用Matlab画出照度数据 Y'":OW#oN  
    8. 在Matlab计算照度平均值 c_=zd6 b$S  
    9. 返回数据到FRED中 &cejy>K
