    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。 P:")Qb2  
    rtz%(4aS  
    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: t3 q0|S  
    enableservice('AutomationServer', true) g[P8  
    enableservice('AutomationServer') /L1qdkG  
    8L?35[]e  
    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 ,&sBa{0  
    %@{);5[  
    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: e FPDW;  
    1. 在FRED脚本编辑界面找到参考. K/y#hP  
    2. 找到Matlab Automation Server Type Library 'lU9*e9  
    3. 将名字改为MLAPP IdlW[h3`[  
    Iky'x[p,D  
    $siiG|)C1  
    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。 g=;c*{

    or u.a   
    现在将脚本代码公布如下,此脚本执行如下几个步骤: m#'2 3  
    1. 创建Matlab服务器。 > @ulvHL  
    2. 移动探测面对于前一聚焦面的位置。 I hvL2 zB  
    3. 在探测面追迹光线 L44-: 3  
    4. 在探测面计算照度 iaq0\d.[7  
    5. 使用PutWorkspaceData发送照度数据到Matlab $o`N%]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :CN,I!:  
    7. 用Matlab画出照度数据 /._wXH  
    8. 在Matlab计算照度平均值 .(  vS/  
    9. 返回数据到FRED中 6|05-x|
