    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。 L<O"36R  
    nhI1`l&  
    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: {PQ!o^7y  
    enableservice('AutomationServer', true) )jm u*D5N  
        enableservice('AutomationServer') &/{x7;e  
    hgI;^ia  
    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 nI<Ab_EB

    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: 8\9s,W:5  
    1. 在FRED脚本编辑界面找到参考. 5 $:  q  
    2. 找到Matlab Automation Server Type Library z]0UW\S/  
        3. 将名字改为MLAPP A"no!AN  
         Qhsk09K_=4  
         BZs?tbf  
    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。 .+2@(r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: v@;!fBUt  
    1. 创建Matlab服务器。 ;(~H(]D  
    2. 移动探测面对于前一聚焦面的位置。 ~4C:2  
    3. 在探测面追迹光线 e2*Fe9:  
    4. 在探测面计算照度 &+-]!^2o  
    5. 使用PutWorkspaceData发送照度数据到Matlab @g==U{k;t  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 M$+2f.(>k)  
    7. 用Matlab画出照度数据 &Ez]pKjB  
    8. 在Matlab计算照度平均值 Q(7M_2e7  
    9. 返回数据到FRED中 YDdY'd`*
