    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。 :@;6  
    1^tSn#j  
    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: 6~3jn+K$1  
    enableservice('AutomationServer', true) $>(9~Yh0  
    enableservice('AutomationServer') h-,?a_  
    'DeW<Sa~  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Ri[S<GOMii  
    _r[r8M B  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: <B=[hk!  
    1. 在FRED脚本编辑界面找到参考. ,b4~!V  
    2. 找到Matlab Automation Server Type Library n{z8Ao%  
    3. 将名字改为MLAPP qr9Imr0w<  
    J$#D:KaU:N  
    9D%qXU  
    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_ZO^E~D_

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  I}rGx  
    1. 创建Matlab服务器。 zF=#6  
    2. 移动探测面对于前一聚焦面的位置。 q _19&;&  
    3. 在探测面追迹光线 ` %l&zwj>  
    4. 在探测面计算照度 A3<^ U  
    5. 使用PutWorkspaceData发送照度数据到Matlab {dZ!I  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \+G.]|"Y  
    7. 用Matlab画出照度数据 JR!Q,7S2!N  
    8. 在Matlab计算照度平均值 :|zp8|  
    9. 返回数据到FRED中 "wC0eDf
