    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。 '0[l'Dt'  
    1j}o. 0\  
    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: }!2|*Y  
    enableservice('AutomationServer', true) BYu|loc  
    enableservice('AutomationServer') \PL92HV  
    ?g9CeeH*  
    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 62.{8Uj  
    *G=n${'  
    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: 'Y[\[]3[8  
    1. 在FRED脚本编辑界面找到参考. nHA2p`T  
    2. 找到Matlab Automation Server Type Library 0O[q6!&]  
    3. 将名字改为MLAPP  ;v.l<AOE  
    ZM<1;!i  
    r&^4L  
    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。 M5D,YC3<

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?vvjwys@  
    1. 创建Matlab服务器。 <;= X7l+  
    2. 移动探测面对于前一聚焦面的位置。 T1D7H~ \lG  
    3. 在探测面追迹光线 64[j:t=N  
    4. 在探测面计算照度 eE1w<] Eg  
    5. 使用PutWorkspaceData发送照度数据到Matlab eGZId v1  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u U\UULH0  
    7. 用Matlab画出照度数据 lQoa[#q  
    8. 在Matlab计算照度平均值 N-lXC"{)  
    9. 返回数据到FRED中 mz>"4-]
