    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。 .5?e)o)  
    [2~^~K  
    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: hD)'bd  
    enableservice('AutomationServer', true) {S l#z }@s  
    enableservice('AutomationServer') 7\;4 d4u  
    VK)vb.:  
    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 +)J;4B  
    z8VcV*6  
    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: <I 5F@pe'  
    1. 在FRED脚本编辑界面找到参考. yzH(\ x  
    2. 找到Matlab Automation Server Type Library JCe%;U  
    3. 将名字改为MLAPP 9-B/n0

    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。 }Mv$Up

    现在将脚本代码公布如下,此脚本执行如下几个步骤: PH1jN?OEwZ  
    1. 创建Matlab服务器。 v.Vd js  
    2. 移动探测面对于前一聚焦面的位置。 ffH]`N  
    3. 在探测面追迹光线 ]cmq  
    4. 在探测面计算照度 ;L`NF"  
    5. 使用PutWorkspaceData发送照度数据到Matlab >Tf <8r,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xU6rZ CqE  
    7. 用Matlab画出照度数据 f)_k_<  
    8. 在Matlab计算照度平均值 Kb$6a'u7  
    9. 返回数据到FRED中 [@_IUvf^.
