    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。 =V^@%YIn  
    3^G96]E  
    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: ?(im+2  
    enableservice('AutomationServer', true) +CTmcbyOi  
    enableservice('AutomationServer') <uF [,  
    wTpD1"_R  
    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 N5 q725zJ  
    Vf{2dZZ{1  
    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: zd`=Ih2Wx  
    1. 在FRED脚本编辑界面找到参考. 5iWe-xQ>  
    2. 找到Matlab Automation Server Type Library \OHv|8!EI@  
    3. 将名字改为MLAPP =2oUZjA

    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。 4=p@2g2"H

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~5t?C<wo  
    1. 创建Matlab服务器。 $ly0h W  
    2. 移动探测面对于前一聚焦面的位置。 cztS]dcf>~  
    3. 在探测面追迹光线 u3wL<$2[8  
    4. 在探测面计算照度 6D9o08  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~Ob8i1S>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z Z%/W)t  
    7. 用Matlab画出照度数据 G6Q4-kcK  
    8. 在Matlab计算照度平均值 5a$$95oL  
    9. 返回数据到FRED中 IH3FK!>6
