    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。 R(dVE\u  
    11Kbj`sRZ  
    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: n[zP}YRr  
    enableservice('AutomationServer', true) Fv n:V\eb  
        enableservice('AutomationServer') 9Vp|a&Ana  
    /rsr|`#  
    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 )9sRDNr  
    ~GL"s6C$`;  
    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: PZn[Yb:  
    1. 在FRED脚本编辑界面找到参考. ?`+46U%  
    2. 找到Matlab Automation Server Type Library N 3IF j  
        3. 将名字改为MLAPP RhM]OJd'

         )+]8T6~ N  
    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。 2#z6=M~A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ]d#Lfgo  
    1. 创建Matlab服务器。 _akC^h T  
    2. 移动探测面对于前一聚焦面的位置。 e|:#Y^  
    3. 在探测面追迹光线 vywd&7gK  
    4. 在探测面计算照度 # 4E@y<l$  
    5. 使用PutWorkspaceData发送照度数据到Matlab Z5aU7  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 -uZ bVd  
    7. 用Matlab画出照度数据 (P;z* "q  
    8. 在Matlab计算照度平均值 G{*m] 0Q  
    9. 返回数据到FRED中 %x_c2
