    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。 oB$c-!&  
    tu:W1?  
    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: h3rVa6cxM  
    enableservice('AutomationServer', true) k~XDwmt;  
    enableservice('AutomationServer') HD YWDp  
    fda)t1u\8  
    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 ?D_^8\R  
    Y.b?.)u&  
    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: zhgvqg-  
    1. 在FRED脚本编辑界面找到参考. H{4_,2h =m  
    2. 找到Matlab Automation Server Type Library FI"KJk'  
    3. 将名字改为MLAPP <%N*IE"q  
    p|>m 2(|  
    W+I""I*mV  
    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。 ~5>k_\ G8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: RqKkB8g  
    1. 创建Matlab服务器。 ~5o2jTNy`p  
    2. 移动探测面对于前一聚焦面的位置。 Zd}12HFq  
    3. 在探测面追迹光线 {8"Uxj_6V  
    4. 在探测面计算照度 W1JvLU5L*r  
    5. 使用PutWorkspaceData发送照度数据到Matlab "0Z5cQjg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 H6hhU'Kxf8  
    7. 用Matlab画出照度数据 Oe21noL  
    8. 在Matlab计算照度平均值 wUfm)Q#  
    9. 返回数据到FRED中 /*(&Dmt>
