    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。  *1["x;A  
    pt.V^a  
    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: 5xdeuBEY8  
    enableservice('AutomationServer', true) e&ysj:W5 "  
    enableservice('AutomationServer')  ]Pe>T&  
    Z C01MDIY  
    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 _?O'A"  
    i#b/.oa  
    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: m_0y]RfG  
    1. 在FRED脚本编辑界面找到参考. u@e.5_:S)  
    2. 找到Matlab Automation Server Type Library [k%hl`}  
    3. 将名字改为MLAPP YOLzCnI4  
    +U<YM94?  
    asYk #;z\"  
    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。 r9{@e^Em

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Ed u(dZbKg  
    1. 创建Matlab服务器。 _N|%i J5  
    2. 移动探测面对于前一聚焦面的位置。 [pTdeg;QE  
    3. 在探测面追迹光线 Hj r'C?[  
    4. 在探测面计算照度 ^7+;XUyg  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,L-/7}"VHA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?&wrz  
    7. 用Matlab画出照度数据 oH6zlmqG"  
    8. 在Matlab计算照度平均值 qI7KWUR  
    9. 返回数据到FRED中 \54B
