    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。 vHoT@E#}'  
     U5T^S  
    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: 6B4hSqjh  
    enableservice('AutomationServer', true) 7UY('Q[  
    enableservice('AutomationServer') kvY} yw7  
    QLxXp  
    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 ,<I L*=a

    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: 8kKRx   
    1. 在FRED脚本编辑界面找到参考. 6uv'r;U]  
    2. 找到Matlab Automation Server Type Library <5C=i:6%  
    3. 将名字改为MLAPP t;bZc s  
    ;w>Q{z  
    &^"s=g.  
    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。 :cIu?7A

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~{kA) :  
    1. 创建Matlab服务器。 }j]<&I}  
    2. 移动探测面对于前一聚焦面的位置。 y81#UD9[  
    3. 在探测面追迹光线 Ej9/_0lt  
    4. 在探测面计算照度 ([z<TS#Md  
    5. 使用PutWorkspaceData发送照度数据到Matlab Lcm~QF7cd  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 E0WrpGZ  
    7. 用Matlab画出照度数据 +Px<DX+  
    8. 在Matlab计算照度平均值 n:{-Vvt  
    9. 返回数据到FRED中 |~1rKzZwF
