    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。 A/bxxB7w  
    xXa* d  
    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: 8 `\^wG$W  
    enableservice('AutomationServer', true) N 3M:|D  
    enableservice('AutomationServer') 2 X];zY  
    8S8^sP  
    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 /5x~3~

    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: q,e{t#t  
    1. 在FRED脚本编辑界面找到参考. 1/ZvcdYB  
    2. 找到Matlab Automation Server Type Library Z.Otci>J  
    3. 将名字改为MLAPP <5 Ye')+

    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。 g Kp5*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *8QESF9  
    1. 创建Matlab服务器。 fG *1A\t]  
    2. 移动探测面对于前一聚焦面的位置。 tEU}?k+:j)  
    3. 在探测面追迹光线 \hlQu{q.  
    4. 在探测面计算照度 Gky e  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3CKd[=-Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ffv v8x  
    7. 用Matlab画出照度数据 xH,D bAC;  
    8. 在Matlab计算照度平均值 YsX&]4vzm  
    9. 返回数据到FRED中 k`j>lhH
