    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。 #\*ODMk$4|  
    iD#HB o  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 4(Gs$QkSo|  
    enableservice('AutomationServer', true) 1$e z}k,  
    enableservice('AutomationServer') [TvH7ott'1  
    {;]:}nA  
    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 8=OK8UaU

    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: %m1k^  
    1. 在FRED脚本编辑界面找到参考. kVE% "  
    2. 找到Matlab Automation Server Type Library C#[YDcp4  
    3. 将名字改为MLAPP {C Qo}@.7  
    cZT;VmC  
    a@Tn_yX  
    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。 Lc(D2=%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5*~Mv<#  
    1. 创建Matlab服务器。 &-W5 T?Sl  
    2. 移动探测面对于前一聚焦面的位置。 T1m'+^?"  
    3. 在探测面追迹光线 4thLK8/c5g  
    4. 在探测面计算照度 o-2FGM`*VB  
    5. 使用PutWorkspaceData发送照度数据到Matlab gBz$RfyF  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bs$x%CR  
    7. 用Matlab画出照度数据 @@K@;Jox  
    8. 在Matlab计算照度平均值 #$7 z  
    9. 返回数据到FRED中 awN{F6@ZE
