    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。 nxyjL)!)0  
    i5 L:L  
    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: *b Ci2mbm@  
    enableservice('AutomationServer', true) c{mKra  
    enableservice('AutomationServer') llHc=&y#  
    \-Iny=$  
    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 6wb^*dD92

    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: I%}L@fZ  
    1. 在FRED脚本编辑界面找到参考. Vl{~@G,@  
    2. 找到Matlab Automation Server Type Library @PPR$4  
    3. 将名字改为MLAPP 7_Ba3+9jpa  
    6_R\l@a  
    `E} p77  
    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。 (px*R~}

    现在将脚本代码公布如下,此脚本执行如下几个步骤: tS\=<T  
    1. 创建Matlab服务器。 Ky[bX  
    2. 移动探测面对于前一聚焦面的位置。 5Noe/6  
    3. 在探测面追迹光线 /x  
    4. 在探测面计算照度 3yTQ  
    5. 使用PutWorkspaceData发送照度数据到Matlab 45x,|h[F{5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;".z[l*  
    7. 用Matlab画出照度数据 Qm.z@DwFM{  
    8. 在Matlab计算照度平均值 8To7c  
    9. 返回数据到FRED中 :O9P(X*
