    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。 #kW=|8X  
    Usf@kVQ  
    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: S\:^#Yi`  
    enableservice('AutomationServer', true) 1ubu~6  
    enableservice('AutomationServer') E22o-nI?1  
    oZ%uq78#[%  
    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 ~}_^$l8#-Q  
    P'<i3#;7X  
    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: lju5+0BSb  
    1. 在FRED脚本编辑界面找到参考. puOtF YZ\  
    2. 找到Matlab Automation Server Type Library zVE" 6  
    3. 将名字改为MLAPP wC{sP"D  
    >j?5?J"  
    NN4Z:6W5  
    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。 45JL{YRN

    现在将脚本代码公布如下,此脚本执行如下几个步骤: \lK?f]qJq  
    1. 创建Matlab服务器。 85E$m'0O  
    2. 移动探测面对于前一聚焦面的位置。 :qo[@x{  
    3. 在探测面追迹光线 Mk*4J]PP  
    4. 在探测面计算照度 o9xc$hX}  
    5. 使用PutWorkspaceData发送照度数据到Matlab [Hx}#Kds  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?AFb&  
    7. 用Matlab画出照度数据 li*S^uSF  
    8. 在Matlab计算照度平均值 ;u2[Ww~k  
    9. 返回数据到FRED中 k4s V6f
