    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。 vI pO/m.3  
    dl*_ m3T  
    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: hb /8Q  
    enableservice('AutomationServer', true) 3JlC/v#0  
    enableservice('AutomationServer') vKU]80T  
    "B|nhd  
    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 {+@ms$z  
    LKK{j,g7  
    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: ]Wy^VcqX  
    1. 在FRED脚本编辑界面找到参考. oTq%wi6 _  
    2. 找到Matlab Automation Server Type Library bGGeg%7  
    3. 将名字改为MLAPP CbTf"pl  
    ALE808;|  
    ^G|w8t+^  
    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。 u4Y6B ]Q

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~I8v5 H  
    1. 创建Matlab服务器。 SBCL1aM  
    2. 移动探测面对于前一聚焦面的位置。 (,- 5(fW  
    3. 在探测面追迹光线 S`pF7[%rp  
    4. 在探测面计算照度 g)=V#Bglv  
    5. 使用PutWorkspaceData发送照度数据到Matlab F`YFo)W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >QYh}Z- /%  
    7. 用Matlab画出照度数据  4 "pS  
    8. 在Matlab计算照度平均值 6obQ9L c  
    9. 返回数据到FRED中 L]c 8d
