    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。 A{\7HV5  
    }qT @.  
    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: ui`xgR\6Rh  
    enableservice('AutomationServer', true) 5.F.mUO  
    enableservice('AutomationServer') Q bfm*JP~  
    au}rS0) +  
    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 Y }'C'PR  
    m,aJ(8G  
    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: \bqNjlu  
    1. 在FRED脚本编辑界面找到参考. |M  `B  
    2. 找到Matlab Automation Server Type Library Yi&;4vC  
    3. 将名字改为MLAPP TbU\qcm]]

    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。 lZV]Z3=p'0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rw8O<No4.o  
    1. 创建Matlab服务器。 t*zve,?}  
    2. 移动探测面对于前一聚焦面的位置。 gWqmK/.U.0  
    3. 在探测面追迹光线 jpZX5_o  
    4. 在探测面计算照度 aoz+g,1 //  
    5. 使用PutWorkspaceData发送照度数据到Matlab HnUM:-6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 kf_s.Dedw  
    7. 用Matlab画出照度数据 \% !]qv  
    8. 在Matlab计算照度平均值 f'TjR#w  
    9. 返回数据到FRED中 03J,NXs
