    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。 5_PWGaQa  
    $8EV, 9^U  
    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: Vx}Yl&*D  
    enableservice('AutomationServer', true) )#)nBM2\  
    enableservice('AutomationServer') 2Ti" s-  
    5#yJK>a7  
    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 3j]UEA^

    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: #>MO]  
    1. 在FRED脚本编辑界面找到参考. d3\OHkM0^  
    2. 找到Matlab Automation Server Type Library E~rs11  
    3. 将名字改为MLAPP )RpqZe/h4  
    bnA T,v{  
    M@',3  
    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。 N8Rm})

    现在将脚本代码公布如下,此脚本执行如下几个步骤: a7XXhsZ  
    1. 创建Matlab服务器。 KK&<Vw|O\  
    2. 移动探测面对于前一聚焦面的位置。 x`};{oz;  
    3. 在探测面追迹光线 }:,o Y<  
    4. 在探测面计算照度 {bAWc.  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0A) Vtj$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vjOG?-  
    7. 用Matlab画出照度数据 N/`TrWVF
