    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。 s[yWBew  
    7K1-.uQ  
    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: 5i!Q55Yv=,  
    enableservice('AutomationServer', true) lLx!_h  
    enableservice('AutomationServer') $KiCs]I+  
    $YL9 vJV  
    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 ~RhUg~o

    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: jFj11w1FrA  
    1. 在FRED脚本编辑界面找到参考. K,E/.Qe\C  
    2. 找到Matlab Automation Server Type Library .+9hm|  
    3. 将名字改为MLAPP Dqx#i-L23

    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。 Z*%;;&?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3S0.sU~_U  
    1. 创建Matlab服务器。 Td=4V,BN  
    2. 移动探测面对于前一聚焦面的位置。 -/yqiC-yx  
    3. 在探测面追迹光线 _R4}\3}!  
    4. 在探测面计算照度 )`\hK  
    5. 使用PutWorkspaceData发送照度数据到Matlab U v2.Jo/Q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `ONjEl  
    7. 用Matlab画出照度数据 @I _cwUO  
    8. 在Matlab计算照度平均值 9wgB J Jl7  
    9. 返回数据到FRED中 e~o!Qm
