    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。 GNJ /|9  
    Z^>4qf,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: wY<s  
    enableservice('AutomationServer', true) r &.~ {  
        enableservice('AutomationServer') ?>B?*IK!  
    q@wD@_  
    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 c]u ieig0~

    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: ;O}%SCF7  
    1. 在FRED脚本编辑界面找到参考. \8xSfe  
    2. 找到Matlab Automation Server Type Library on 7 n4  
        3. 将名字改为MLAPP q TJ0}F  
         `PbY(6CF  
         ^t})T*hM0  
    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。 %'1iT!g8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3Z" ;a  
    1. 创建Matlab服务器。  4v`/~a  
    2. 移动探测面对于前一聚焦面的位置。 HS <Jp44  
    3. 在探测面追迹光线 m+!.H\  
    4. 在探测面计算照度 5[4wN( )  
    5. 使用PutWorkspaceData发送照度数据到Matlab x[58C+  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 M*0^<e~]F  
    7. 用Matlab画出照度数据 Ca'BE#q  
    8. 在Matlab计算照度平均值 $rXCNew(  
    9. 返回数据到FRED中 I#2$CSJ
