    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。 D!Owm&We  
    ^j[>.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: -1Yt3M&  
    enableservice('AutomationServer', true) >#Y8#-$zc  
    enableservice('AutomationServer') I5wf|wB-  
    `][~0\Y3m  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 K8XXO"  
    {UQpD   
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: D@rOX(m  
    1. 在FRED脚本编辑界面找到参考. <@.f#  
    2. 找到Matlab Automation Server Type Library 3:&!Q*i;  
    3. 将名字改为MLAPP 2BS2$#c>

    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。 z `T<g!Y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: T|GRkxd,E3  
    1. 创建Matlab服务器。 Y\(Q  
    2. 移动探测面对于前一聚焦面的位置。 yyPkjUy[  
    3. 在探测面追迹光线 8iB1a6TlL  
    4. 在探测面计算照度 bqJL@!T  
    5. 使用PutWorkspaceData发送照度数据到Matlab yd]W',c  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4Smno%jq  
    7. 用Matlab画出照度数据 6k%N\!_TUW  
    8. 在Matlab计算照度平均值 lRi-?I| ~9  
    9. 返回数据到FRED中 30-XFl
