    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。 v8fZ?dx  
    ~PAbLSL*u  
    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: !\k#{ 1[!  
    enableservice('AutomationServer', true) sxQ,x/O  
    enableservice('AutomationServer') 4[EO[x4C  
    ,E8>:-boL  
    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 eS# 0-  
    \3Ald.EqtM  
    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: #]\G*>{  
    1. 在FRED脚本编辑界面找到参考. uxJiec`&  
    2. 找到Matlab Automation Server Type Library 6pz:Lfd80  
    3. 将名字改为MLAPP q2U"k  
    ` Ehgn?6'

    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。 N4]6LA6x6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;<)-*?m9  
    1. 创建Matlab服务器。 Gt%?[  
    2. 移动探测面对于前一聚焦面的位置。 tlxjs]{0E  
    3. 在探测面追迹光线 Hr,gV2n  
    4. 在探测面计算照度 ]}Hv,a   
    5. 使用PutWorkspaceData发送照度数据到Matlab \,#4+&4b  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 nhxd  
    7. 用Matlab画出照度数据 o?hw2-mH  
    8. 在Matlab计算照度平均值 G.E~&{5xQ  
    9. 返回数据到FRED中 ~4X!8b_
