    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&u;kh4g  
    \Dn47V{7-  
    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: 4DLp +6zP  
    enableservice('AutomationServer', true) v$n J$M&k  
    enableservice('AutomationServer') ?so=k&I-M  
    6>  L)  
    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 vH[G#A~4  
    _Fc :<Ym?  
    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: /kZ{+4M  
    1. 在FRED脚本编辑界面找到参考. >{ /As][  
    2. 找到Matlab Automation Server Type Library $nf5bo/;  
    3. 将名字改为MLAPP %1JN%

    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。 [nYm-\M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: LA +BH_t&  
    1. 创建Matlab服务器。 pYxdE|2j  
    2. 移动探测面对于前一聚焦面的位置。 `S)*(s?T  
    3. 在探测面追迹光线 h=a-~= 8  
    4. 在探测面计算照度 mK Ta.  
    5. 使用PutWorkspaceData发送照度数据到Matlab !Py SYY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \jR('5DcB  
    7. 用Matlab画出照度数据 k'6Poz+<  
    8. 在Matlab计算照度平均值 = n>aJ(=Pd  
    9. 返回数据到FRED中 BdMmeM2h
