    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。 FqbGT(QB0  
    +<p&V a#  
    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: {vW0O&[  
    enableservice('AutomationServer', true) Pi?G:IF  
    enableservice('AutomationServer') Lm`-q(!7w  
    }2RbX,0l9  
    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 EFVZAY"+!;

    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: +l)t5Mg\  
    1. 在FRED脚本编辑界面找到参考. ]W Yub1  
    2. 找到Matlab Automation Server Type Library U&R)a| 7R  
    3. 将名字改为MLAPP qCrpc=  
    'do2n/  
    FT6CKsM"  
    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。 vO9=CCxvq

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;Krs*3 s  
    1. 创建Matlab服务器。 /P9fcNP{y  
    2. 移动探测面对于前一聚焦面的位置。 PbvA~gm  
    3. 在探测面追迹光线 v07A3oj  
    4. 在探测面计算照度 #P}n+w_@  
    5. 使用PutWorkspaceData发送照度数据到Matlab o@360#njF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JK!`uG+v  
    7. 用Matlab画出照度数据 ESoC7d&.K{  
    8. 在Matlab计算照度平均值 Gq[5H(0/c  
    9. 返回数据到FRED中 ALF21e*n
