    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。 HgATH  
    7c]Ai  
    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: 7-IeJ6,D  
    enableservice('AutomationServer', true) 1`_)%Y[ZJ  
        enableservice('AutomationServer') &FF. Ddt{  
    `DllW{l  
    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 DF|lUO]:

    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: vl~   
    1. 在FRED脚本编辑界面找到参考. y/6LMAI  
    2. 找到Matlab Automation Server Type Library Od]xIk+E  
        3. 将名字改为MLAPP KL"L65g&  
         ]]o[fqD-Zn  
         VX[!Vh  
    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。 5g>kr< K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: hBE>ea  
    1. 创建Matlab服务器。 5@%-=87S  
    2. 移动探测面对于前一聚焦面的位置。  ly%B!P|  
    3. 在探测面追迹光线 "]V|bz o0a  
    4. 在探测面计算照度 yZ0ZP  
    5. 使用PutWorkspaceData发送照度数据到Matlab emPm^M5/K  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 H^:|`T|,  
    7. 用Matlab画出照度数据 ~Fb?h%w  
    8. 在Matlab计算照度平均值 &it/@8yH  
    9. 返回数据到FRED中 z35Rjhj9
