    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。 gP2zDI   
    v(1 [n]y  
    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: @ ^{`!>Vt  
    enableservice('AutomationServer', true) ~g{j)"1  
    enableservice('AutomationServer') ;c!> =  
    PG&t~4QM`  
    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 nip6|dN

    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: RM;a]g*  
    1. 在FRED脚本编辑界面找到参考. Rx-\B$G  
    2. 找到Matlab Automation Server Type Library u]yy%@U1  
    3. 将名字改为MLAPP fVbjU1N

    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。 i,6OMB $

    现在将脚本代码公布如下,此脚本执行如下几个步骤: W$4$%r8  
    1. 创建Matlab服务器。 J p'^!  
    2. 移动探测面对于前一聚焦面的位置。 yf&g\ke  
    3. 在探测面追迹光线 #l=yD]t PU  
    4. 在探测面计算照度 CX|W$b)%  
    5. 使用PutWorkspaceData发送照度数据到Matlab L@N %S Sf  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4V@%Y,:ee  
    7. 用Matlab画出照度数据 d_9 C m@  
    8. 在Matlab计算照度平均值 gv*b`cl  
    9. 返回数据到FRED中 eZ'8JU]
