    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。 w|M?t{  
    zxj!ihs<  
    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: x:@e ID  
    enableservice('AutomationServer', true) ^@)+P/&  
    enableservice('AutomationServer') 3O]e  
    adxJA}K}  
    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 -x RsYYw  
    F-ZD6l9O  
    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: q|j;dI&  
    1. 在FRED脚本编辑界面找到参考. 7IvCMb&%R  
    2. 找到Matlab Automation Server Type Library PffwNj/l  
    3. 将名字改为MLAPP GRs;-Jt  
    d }]b  
    -OziUM1qs  
    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。 u&g} !Smc8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !<~Ig/  
    1. 创建Matlab服务器。 hR?rZUl2M  
    2. 移动探测面对于前一聚焦面的位置。 jLEU V  
    3. 在探测面追迹光线 R8?A%yxf  
    4. 在探测面计算照度 QzS{2Y[OQ  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;Lu}>.t  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;J`X0Vl$  
    7. 用Matlab画出照度数据 ?r@ZTuq#  
    8. 在Matlab计算照度平均值 .a^/r'?  
    9. 返回数据到FRED中 uIba{9tM"P
